It's okay, I can do it for you if you want

If you look at my post, you'll see that I asked if you would like
me to do it

I will present you a draft here if you like and see how it goes.
No need to waste time of that since I think that using current "Status" column should be enough.
As far as I can tell a lot of the threads in the original post are now somewhat cleaned apart from a few exceptions which will take a little longer to go through. I've likely revisit them from time to time to see if we've got any new spam waves, though judging by the activity of a lot of them, I suspect whoever has been behind the spam waves have either quit or moved on.
Majority of those threads simply cancel that bumping service when they see that their thread is going nowhere and posts have been deleted constantly day after day. But yeah, it's not a bad idea to revisit the threads occasionally as some of them will attempt the same thing, thinking that they lost the attention.
