I hate myself for doing this and joining in, but please read this and have a think about it.
Every time I log in there is a whole load of threads either started by IN or about IN. It is driving people bonkers and they are getting fed up with it. That is the point of what is happening. Rather than either being a total troll or flamer, the person is mucking about with everyone. It is causing a lot of people to get really fed up with coming here and seeing the same thing all the time.
That is the point of doing it. It makes the forum less attractive and drives people away. Not the hard core members (though they will go eventually) but new or newish members will just think, nah this is just boring.
The only way to deal with this (if you really want to) is to ignore it. If there is shit going on you don't have to take part in it, even if other people do. Just decide that you will ignore it. If you have to do something, then report crap and let the mods deal with it. Joining in just keeps the whole thing going on and on and on and on etc.
