Reminder for those that have forgotten: activity requires at least one post per 2-week period in order to gain the potential (and subsequently true) activity. Erase all those posts... and poof, you've used maybe 5% of the amount of time that they have to rubberband them back to 0 for that period.

Not really. There's a couple of users who have just started frantically spamming the report queue recently with hundreds of reports a day probably because theymos announced the possibility of merit badges. It's clear some of them are actually just looking for things to report because they're reporting old threads that haven't been posted in for ages just to be 'locked' or spam posts from ages ago. Just saw one report from January on a spam post. Is that really essential? Nobody will see or miss that post whether it's there or not. Do I really need to waste my time deleting hundreds of posts long buried in a bounty thread? All it does is swamp the queue with things that are either going to take a long time to handle or not get handled at all and increases the chances of us missing something important that needs handling urgently.
