Three possibilities (which applies in general):
1) He doesn't believe that he did anything wrong. He perceives the problem as due to others having built up a bad perception, and thus he can change his screen name and move forward. In real life this is sometimes people's attitude, and it's also sometimes reality.
2) He is in fact trying to change, but not succeeding as habits are deep. Think of an alcoholic who says that's not drinking anymore, then proceeds to drink.
3) He is misdiagnosing his problems. Lots of people do this lots of the time, it's genuinely difficult.
The above applies to the humble bragging and other related traits. Lying about how he was banned is just bizarre. I don't want to be mean, but I'm visualizing a four year old caught with his hand in the cookie jar.
Well yes, of course he doesn't believe he's done anything wrong, I think he has serious problems addressing faults with himself. I once went back and forth several times, trying to make him see a simple point related to humblebragging (I can't remember entirely, but it was to do with making a completely off-topic point but vitally included a part about his success- so that was the whole point of his post) and he just refused to understand a very simple point.
I thought he was doing it intentionally but someone else pointed out that this may just genuinely be how he is, his brain can't quite understand that criticism.
So that's why his apologies never really mean much to me personally, nothing's changed.
And often with people (not necessarily him, but generally) they can apologise and come away feeling even more of a victim for having to admit fault when they don't truly feel there was any, often resulting in further passive aggressive behaviour.
Since when is humble bragging even a crime? People can humblebrag all they like. It's not like there should be a forum rule against passively saying something good about yourself. Or playing dumb.
Sharing pictures and lying about why you got banned is a different thing.
Otherwise, I say humblebrag away if it makes you happy. Ignore it if it doesn't.
It's not very healthy when you need and crave validation from strangers, if that's your way of feeling you have "status" that probably needs to be re-evaluated. I often get the impression from these types that they live a life that revolves around seeking constant validation.
Of course I don't really care about anyone's health in this circumstance, it's plainly just annoying to read. You think you're reading a constructed point and then in paragraph three there's that little reminder he gets laid.
I know we all have to write about personal anecdotes and we can't deny what our lives are, that's different to intentionally bringing up anecdotes that are barely related, just as a reminder of your status in life.
The only thing I should add about Johnson is that at least he doesn't do it to make others feel insecure, he doesn't lol at incels or virgins or anything, he does just seek that validation for himself but the positive thing is that he's not out to make others feel sh*t. I bring this up because it's often the intention of the classic humblebragger, so I should at least make the distinction that he doesn't have this sort of superiority complex at least, he just wants to feel better about himself.
