I just found out that Mantis is not troll resistant bug tracker. I haven't noticed that in default configuration any reporter can "remind" all registered users and make them monitoring any issue. And there is no way to stop monitoring from Mantis. This is exactly what happened to bug 161.
I removed them using phpMyAdmin and I hope that I didn't break anyting. As next I disabled reminding for reporters in Mantis and I hope I didn't upset too much people. If I did, I'm really sorry.
Update: It looks that user was only too impatient and expected reply…
