Really, @redsn0W?
Does it mean that signature will be removed with 30-days ban?
I ask because @Hhampuz still was able to wear signature with his 7-days ban.
I have an assumption that signature will only be removed if one banned due to plagiarism, for rest reasons (non-plagiarism) and different temporary bans (from 7-days, 14-days to 30-days), users can still wear signature.
If you visit his profile, you can see that he got a 2-year-long signature ban:
"Banned from displaying signatures until February 02, 2021, 08:16:07 PM".
I think some unbanned users ended up with shorter, 12-month-long signature bans.
