Recently, a bunch of accounts with strange usernames have been registered on jabber.rueckgr.at. The characters 0, _, l, m, n and r occurred very frequently in these usernames. Their passwords were either "CATSY" or "simpler".
As I think these accounts are used by some kind of Jabber bot, I removed these accounts. Any accounts using the passwords "CATSY" and "simpler" will be removed without any further notice.
If you want to register a large number of accounts on this server for use with bots, you are allowed to do so, but please inform me beforehand.
