Sorry this was not intentional or meant to be personal.
Recently this forum has had a flood of spam bots finding their way past the spam protections.
In tweaking the automated anti bot/spammer a rule got put in that was missing a character.
Instead of banning a single email address, it banned an entire domain.
Also, since spammers and bots use VPN *a lot*, a significant amount of the commercial VPN IP are blocked from signing up a new user.
