I had a bidder the other day, for example, who was listed as having logged in from three different countries in the last 24 hours. Nor did he have any feedback. There was an additional warning that he might using multiple user names. I rejected this bid, as it was fairly obviously not legit. However, I've also had a few other bids from people who have just signed up to Flippa with no feedback rating. They do, however, have a verified phone number.
I'm wondering if any experienced Flippa sellers could tell me what criteria they use when deciding whether to accept or reject a bid. Someone has to sign up sometime, so being new doesn't automatically mean one is a scammer. Do you give such people the benefit of the doubt, or is it safer to only accept bids from established buyers?
