@ArturKirkoryan Because I posted a riddle here which had previously been published on a site I co-own, and included attribution to that site. (I also had a more ... colourful history which had led to previous suspensions, but that was what prompted the last, year-long, one.)

@ArturKirkoryan Hello! :-D

@Randal'Thor I see, better be careful now, our moderators are not joking:)

@ArturKirkoryan Well, I made them a puzzle today ;-)
