guild chat is the best place imo i'll gladly spam this bitch up one day with u making random posts etc but the more people the better looks less incriminating.
i used to spam for hours just pages of me posting getting +1's in my friends guild chat with/without other people. thats were most of my posts came from
now ofc if i ever got caught 10% easy but it would have been worth it, but luckly i never got caught for those.
another good forum is trophy room, +1's and u get to look at godly gear ='s win imo
