Back when I was active filling requests, I simply ignores anyone with junior member tag status.. Most leechers dont change that. The default stays until the users have more then 100 forum posts.. Of course, at that time, we do have one guy who requested on average 1 signature per day which is a source of constant hilarious topic of discussion between me and Riker at that time, because he usually targets either one of us alternately
He did now joins the GD group and have his own signature thread that he made himself, so its kinda moot point right now
If I'm feeling a bit hardworking
I usually peeked at the requester's post trail. <- I still use it to determined when peoples tries to add me as their friends.
