I just ran into this issue, not sure yet if I am just blind or if this really happens ? I have a couple new spammers everyday submiting posts. Now I have discovered a spammy Forum-post and I deleted that post via the "Delete"-button and clicked onto "Permanently Delete". So this is working fine and the Forum-post is gone, but the strange thing is: I can not find the user itself anymore. The username just disappears. I have searched in ACP for that username, but it is nowhere to find....... I wanted to look for that spam-username in order to ban him via the Spam-Cleaner, but now I can not find this username in ACP anymore. I do not know whether the username was "confirmed" or not. Did anyone of you guys experience the same ? It does not happen always, but this happened now twice in the last few days where I could not locate the username anymore. Re-production-steps: 1) you see a spammy Forum-post. 2) go to the Forum-post and click onto "Delete", then "Permanently Delete". 3) fine, the Forum-post is deleted. 4) Now go and find the username of that spammer in ACP.
