If these bots are bumping the treads with posts in every 5-10 minutes, you just won't be able to report (and mods to delete) the posts in time before the next bumping post if I understand it well.
If you report the most recent post, by the time it gots deleted, a new bumping post will come and the whole work with the previous post would worth little because the topic would still be on the top, thanks to the new bump...
We need something else for the bumping bots because pure reporting seems just waste of time and resource...
What happens if we start to deal with topics instead of individual posts?
Let's say if a topic has 100 posts in it and 10 of the posts has been reported (and deleted by a mod), it means it's not a 100% topic, but just 90%. If 50 posts are deleted, the topic is only good for 50%.
If a topic reaches the 50% in reported posts, worth locking or delete or anything...
I know that bumping bots and shills could use this to kill the competitor topics, but in the ANN section this is the same with bumping the first 10 topics, all of the others are nearly killed because people just can't find them on the first few pages...
Just an idea...
