UCEPROTECT is just horrible, full stop. Stuff like [1] read like it's written by a 13 year old. Lots more where that came from; as near as I can tell UCEPROTECT is run by a single person who is consistently vitriolic like this to anyone offering even the mildest of criticisms (supposedly multiple people have involved over the years, but their, ehm, distinct colourful personalities are so alike that I'm inclined to think it's just the same person using different aliases).
People have been complaining about this for a very long time; as long as I can remember. In the past they've also just permanently added people's IPs after complaining their IPs were wrongfully listed (not sure if they still do that).
The UCEPROTECT blacklist should be blacklisted by everyone. Yes, we need a blacklist of blacklists.
