Hi, not quite resolved as such, but it's not bothering me quite as much.
It's working but still painfully slow loading the lists (usually over a minute).
However, I've changed the blocking time to 30 days, which gives it a little more breathing room. Plus, it seems that most of the entries are now permanently blocked, so I seem to have got to most of them... it would still be nice if it moved these to a separate list though!
At least it's blocking all this crazy crawler action, so that's good! Helps to relieve the load on my server somewhat :)
Thanks
