I can actually tell you about the reason behind the “facebook popup”; the weird ip address showing in the stopforumspam.com redirect could be a bad install of the plugin on someones wordpress or other cms (i only mention wordpress because that and phpBB/smf are the popular ones with plugins for it)
The thing with 00webhosting, 50webs, and any of the free web hosting is that since they are free, they are a playground of illicit activity. It is way easier for the processing system in some sites that protect against known evil to block the whole of the hosting service.
And it isn’t all of the domains provided by these services.. but once someone starts bhaving badly from one of them, they block it all – not just [evildoerHostname].whatever.com bit anything.whatever.com…
I find these pop up from time to time in our corp firewalls, i just look at what caused it and block that single host… *shrug*
