during Server switch (2016-12) and forum-/game-database merge, we tried to find a balance, letting old registered forum-accounts (last activity = -12 months) activate their accounts.
These days more and more new accounts collide with old forum accounts. So we decided to completely delete these old forum accounts. It affects forum accounts, where the last visit date is before 2016-07-01.
