Recently a user asked a question on Meta asking about his deleted account (I won't draw attention to him or his question unless it is really necessary
but shouldn't be hard to find - at least until the question gets deleted1 as I don't know if it is relevant to this question).
However, while looking at his account, it appears as if he received the association bonus on all of his accounts, including the new Stack Overflow account he just created, but does not have any account with >200 rep.
The most likely scenario is that the deleted account had more than 200 rep and triggered the association bonus, but that leads to 2 questions:
- Why did his previously associated accounts retain the association bonus?
- Why did he get an association bonus on his brand new account?
1 - The post in question was deleted by the OP several hours ago but before then the account was confirmed by a mod to be deleted due violations of a sock puppety nature (which I think everyone suspected at the time). Given that the account in question was a sock puppet, I think it highlights an important reason for removing the association bonus when the account that triggered the bonus is deleted. Theoretically, as long as he keeps getting the association bonus, he can go to any site and already have more than enough privileges to do damage.
