I have not, but I've got a little experience with it. A good friend of mine (over 20 years of friendship) has a really sweet son who is VERY big for his age. His father was 6'4" pretty early, so it wasn't a surprise. But she'd always get disapproving looks from others on the playground, like her "big kid" should go play with kids his own age, or he's being too rough (he was really just more awkward, tripping on his feet, like a puppy), or he should get off the swing and let a little kid have a turn (when he'd only been on a few minutes). It was hard for her in that she understood that they didn't know his age and that he had every right to that playground, but she also felt a little defensive of him. More is expected out of him than other kids his age, as everyone thought he was 7 or 8, instead of 4 or 5. They'd think he was slow since his speech wasn't what they'd expect, or if he behaved as a 5 year old instead of a 3rd grader. Now he's 14, a nice kid, and very very popular with the girls in school, but he does have some issues keeping his thoughts to himself (or thinking about them a bit, organizing those thoughts into words that won't be misunderstood). She doesn't really know how to deal with teaching him to censor himself....but that's the issue now, with teachers.
There was a lady that went to a playgroup we attended for awhile. She was VERY nice, she was from another country and new to the area. I didn't know anyone else from where she was from, so I know she must have been a little lonely. Her son was a young guy (2, MAYBE 3) but a stout, sturdy little boy and very....."hands on". He would get really excited and squeal, but then slap or push. That's not ok. She'd try to stop him, but he'd do it A LOT. After a few times of my small 2-3 year old son getting knocked down, I called him over to eat some lunch. As we were eating I said "the guy in the orange shirt: he's just trying to play, but he plays too rough. I think you should either say "stop now" or if he won't stop, move to the other side and play away from him a bit". I said it quietly and casually, making sure not to blame the kid for being "bad" (especially when watching his face I saw that he wasn't being mean or angry, he just couldn't control his excitement being with other children). But other moms got mad at her for not doing enough. I couldn't tell if it was cultural, a parenting style, or what, but I noticed that the mom started being isolated. Like, others didn't like how her child behaved so they did start sitting away from her. They'd give her looks but not say anything. I felt bad so I sat with her from then on. It was obvious she wanted adults to talk to, she felt alone and her husband worked a lot, she was a little overwhelmed. I started calling my son over for little things to correct him in front of her, just as sort of a model. She started doing that too, but it didn't really work on her son. Then he pushed a girl down, and someone got really mad, she grabbed her son and left. It's the last I ever saw of her, but I feel bad for her. I don't know what I'd do if I was actually in her shoes.
The people across the street have the first child I'd consider someone I don't want my kid playing with. But it's not all his fault. He's left to play outside alone all the time. He JUST turned 4 and crosses the street without looking, plays IN the street (and won't necessarily move if you're driving--more than once he's actually stood in the middle of the road with his hand up to "stop" people), and I see him in the woods behind our backyard, which I have issue with because there ARE snakes back there. I don't mind so much if he's very close to our fence but just about 10 ft further back there's a little ditch that we know for sure has snakes (and small alligators at different times of the day during the summer are probably about 30-50 ft back). If I see him going a little further than my fence I'll call out to him, but he just sneers at me like I'm stupid for talking to him. Lately we've been finding stones in our yard and I suspect he's throwing them in there---I HOPE it's TO our dog and not AT our dog (like, *hopefully* trying to get her to fetch? I really hope nobody is chucking rocks at our dog). I haven't caught him doing that though. When we first moved here, we let my son go play in his yard; it was the first time we'd ever let him be across the street at someone's house before, but we were trying to follow their lead. We kept an eye on them though, and saw him kick our son hard between the legs (and he's a good 6" taller, and 10-15 lbs heavier than our son). We've seen other things not involving our kids, so our son isn't allowed over there. We get along fine with the parents, but our parenting styles are so different that we don't hang out. When our son is at our other neighbors, this kid from across the street goes over too, and has pushed and held my son down a few times. Joseph didn't do anything about it because he didn't want to be "in trouble" but I told him "That's what you're in Kung Fu for----this has become a problem. Look him straight in the eye and say "Do NOT do that again". If he does, take him down". Joseph warned him the next time, the kid laughed at him, so he did a hard take down. They play nicely now, but at arm's length. I feel a little bit bad, we don't invite them to the parties or anything, but then they have said so themselves, that their son is a bit of a bully. If I knew that about my son, I'd be standing outside as he was playing to catch him so I could instruct and train him on how to behave, but they don't. I guess that's the difference and why I don't include them as much.
ETA: From the description given, I'd sayTracy K's kid is NOT what I would call a bad kid. I would call that me, and my brother. And while tiring, fun too.
