@superclopez see the OP. If it ask you to join one of their Steam group, there is a Rex on the group icon, it is ban. Note that Marvelous can do some GA whout asking to join one those group but as they are new REX Network site it is not allowed.
Np, everyone can make a mistake. To see if a GA have already been posted you can take the direct link and search for what is after gleam.io, so here it is lD8lb (https://gleam.io/lD8lb/free-3-games-pack).
