I have seen you Mattelot use your alts “Forums” and “Stenbjorn” to like repeatedly your own posts. Since you use sock puppets, I wonder if that is the reason why you frequently and inaccurately project that the forum has a sock puppet problem.

Tell-tale signs are your zero post accounts with hidden profiles that are used to cover up the list of likes given (since it is primarily to your main account Mattelot)
This is a link to Stenbjorn posting on Blizzard’s Diablo:Immortal Forum.

Edit: Mattelot does not deny that these are his sock puppet accounts.
