On the notification/email there was this information: More topics may be posted, but you won't receive more email notifications until you return to the board and read some of them.
Therefore I thought that I would need to read and reply the topics to keep receiving more notifications on my email.
Notice how the mail just said you had to "read" some of them? It didn't say you had to actively controbute to them.
I'm guessing this has probably happened to other users before though.
I'd strongly suggest you don't post anywhere else until you get a response from a moderator on this, BAN EVASION (posting on a board other than meta is against forum rules while you have a ban and ALL accounts will be permabanned).
