From a sellers point of view:
Make sure those who bid the auctions have money. Make them post some up, escrow, verify bank statements, whatever, and compensate auction winners who have to deal with time wasters.
I have a few sites I can sell on flippa. But I had previously tried to sell 2 on flippa and in each case, the guy who won the bid didn't pay.
The sites were legit too. 100% real, everything exactly as advertised (I was even upfront about issues most sellers wouldn't mention) - Both were quality sites, not some auto blog or turnkey crap.
I spend quite a bit of time handling requests for proof, answering questions and checking potential bidders to see who they were and if they were legit. If I straight up sold that time I could likely make a little less, and still keep my sites (sites were for mid x,xxx USD)
One of the two fuckheads who didn't pay wasn't even banned by flippa because "I didn't give him enough time to pay" even though I disputed the transaction only after the loser started talking about how he didn't have the money to pay what he bid.
I mean, I could still make money selling sites on flippa, if I wanted to spend so much time to get so little ROI. But who wants that?
Also, make sure to vet the sellers and have a minimum standard.
I've wanted to buy shit on flippa as a client also (I actually bought one site), and the low quality of listings discouraged me from buying anymore.
I wanted to buy two types of sites:
1- Low cost, well aged pumpers - Basically, any decent site that has some unique content and has been in the Google index for 5-15 years without interruption (no drops) and has non-spammy links. I gave up. There are just too many bullshitters. The few that looked interested were too expensive
2- Low 5 digit income generating sites - I couldn't find anything legit. I was willing to pay xx multiple of income too, depending on how stable. But I just kept checking worthless crap after worthless crap.
I get the feeling that flippa is 99% WaFo users buying and selling shit to each other.
In example:

The few ones that are worthwhile I end up feeling I can set the same thing up for half the cost of buying.
I think there is a need for a platform to buy and sell quality online properties that are worth $x,xxx to $xxx,xxx - Those multi-million dollar ones aren't going to be sold at auction any time soon IMO.
