I'd say it's a little premature to say that someone "doesn't pay" just because it is still pending after 14 days. As Playa mentioned, they have 30 days to approve. Yes it is nice when they pay within a few days, but sometimes it just takes longer.
I have a pending hit from that same requester from the 19th -- and from his reviews on TO, it looks like they just auto-pay after 30 days.
I'm still waiting for a payment from a different requester from June 8th. Figure they have a few more days and possibly they are auto-pay at 30 also.
Appreciate the replies here...I was starting to get concerened since one of mine from this requester just hit 30 days and no payment yet...will look for it!
