Tapatalk, the worst system I have ever encountered, it's more aimed at gadget users and attempting to get people to fork out cash or earn points, Ignoring them and using an adblocker seems to work so it doesn't need to cost anything.
I moderate on a forum they swallowed up, we now have about 4 members left out of a few hundred, if and when they go I will be dumping it. Another forum I used to use which was a Free Forums one has lost all it's members and is dead, loads more gone the same way. When they took over the forum I moderate on when it actually worked, took months to sort out their server issues, they lost all our images, screwed up permissions, killed of the Chat room we had......... And keep spamming me with info on the latest Tablet crap they are adding. As you have probably gathered I'm not a fan, at least with 4 people there is no need to moderate these days, Just as well as I'm the only one left apart from the forum owner out of six!
