ags trust system must detect steam trust system
if not, even old account is not ags trusted
and must buy something from lost ark store to get ags trusted
check this post case here : Unable to get trusted status
The 30 days restriction is useless because if you think about it there is no reason bots have not pre-made thousands of steam accounts months ago in anticipation of something like this. That said they still have to put in 5$ to make it trusted which is unavoidable but I am willing to wager that on average they make back more than that 5$ investment per account so they are probably willing to do it.
Though if Amazon bans the bots faster than they can make a profit from them they will probably start being more careful about their bot practices.
