My main concern about this is why is it that mainly newbies are the ones making this offer ?
Coz most probably they don't have an account yet in this forum or they just don't want to use their main account to avoid tagging -ve.
Like seriously, I have been following up with all this and most of them that come here to make some offers are just newbies and that makes it very suspicious, meaning they are likely to be scammers.
So they should have a higher ranks, jr to legendary so it will not be as suspicious as you said when they offer such.
Whosoever make such offer if it's requiring an extraordinary task and rates, 100% it's a scam.
