After some people complained that they were also a member on Eupedia, all the inactive members (those who didn't post on Eupedia,those which requested so) were deleted from Eupedia. I don't know why some of you were also banned as you were active (or pretty much active) I might have been a mistake perhaps, you can always pm him asking why

Btw, Maciamo posted a thread saying he removed inactive users, here it is :
