Not sure if its still valid that they are spammers but it looks like this guys are related to the recently banned LoL spammers, however this guys have not posted in the forum recently
Pattern is they post together but not all them in 1 thread, like malzahar will be followed by malphite, lissandra will be followed by luciann, olaf with orianna, then nunu with olaf, they are all registered May 28, 2014, all Full member, all under 1 signature campaign... and they are all League of Legend characters
