Like many of you I have recently suffered a spate of Spammers, mainly spam bots of the X variety!
After trying a number of different add-ons that I either couldn't get to install, or which just didn't work, I was lucky enough to be contacted by an old friend Dan Cryer, who has created a service, that is I believe exactly what XF needs, should in fact be built in.
This service is totally free, dead simple (sign up at the above site, download the package, unpack somewhere logical, then get a license key, and just upload the B8SpamService folder into the library folder and install the add on via the browse function in the ACP, then input the license key into the Options/Block 8 Stop Spam, and you are done! ) and adds no drama or extra effort to your life!
Utilizing the StopForumSpam, CloudFlare and their own database to prevent spammers from registering in the first place in a seamless way.
So far in the few days I have been using it, not one spammer has registered! Woo Hoo! Exactly what I was looking for, something simple, clean, easy!
Check it out if you are after the same anti-spam capabilities!
Cheers and Thanks Dan for a great product!
