The user at meta.mathoverflow.net/users/141826/phd recently got a 100 point association bonus (15 mins ago?) even though they only have one account (MathOverflow).

In comments at meta.mathoverflow.net/q/4261/12357 , the OP claims that they have more than one account, but have hidden the others.
@MartinSleziak Oops, I didn't see that you already addressed this.

Yes, I see that you have exchanged some comments about this. (As the question might be deleted, perhaps there's no harm in copying them ehre.)

@phd, thanks, I didn't know that communities can be hidden. (To those interested, see meta.stackexchange.com/users/hidecommunities/current .) — Joel Reyes Noche 2 hours ago

I have also searched a bit whether there are some Meta Stack Exchange posts related to similar problems (association bonus and bounty, repeatedly deleting account and getting association bonus for a new one, etc.)
Q: Association bonus is still awarded if accounts are deleted
