PM me which one was blacklisted and I'll look it up and see if I can remove that.
After googling about it, it seemed to be caught on some general network blacklist though.
So basically, except RPM, I probably wouldn't be able to enter some other sites.
I don't think you can actually help me with that, but thanks anyway.
Some sites suggest that if something like this happens for no reason, you should of course run some scans on your PC, so that's what I'm doing right now.
