I was trying to put a quiet ban on an IRC user today, but I accidnentally typed /mode #divinelunacy +b ~q: *!sticks1988!@*. The space between the : and the* caused the server to interpret it as a ban on *!*@*, which is everyone in the channel. When I tried to correct myself, I ended up tying /mode #divinelunacy +b ~q*!sticks1988!@*. (I think that's what I typed anyway...) The server interpreted that as #divinelunacy +b ~q:*!*icks1988!@*. I just gave up after that. (I meant /mode #divinelunacy +b ~q:*!sticks1988@*.)
I wanted to add 200 rows to the Mafia Returns database... I have my reasons... I typed something to the effect of
OOps... An infinite loop. It added 30 MB of data to the database and caused 25 minutes of downtime. Oops.
