The PayBis campaign looks pretty suspicious. Their method of recruitment is very strange. Accept users with questionable posts quality, and dont answer to users questions. Owner after 4 hours from running thread is not active. No trustable manager, no escrow, lack of basic informations - very possible scam.
I suggest tag them with *
In other words, they weren't as picky as campaign managers like Yahoo, Lauda, Lutpin, etc. And they were not as active as well. It doesn't prove anything at all. It might have raised suspicion to you, but it doesn't prove anything. There's a campaign (i.e. Orocoin, IIRC) that has behaved the same way. In a matter of 1 1/2 hours prior to the creation of the signature campaign thread, their campaign got filled up. I don't recall them using escrow at all, but still the campaign was successful.
On a side note and as a reminder to other people, it's not our job to keep track or moderate or investigate if the incoming campaigns have a huge possibility that they will scam the users. Look at betcoin.ag and spectrocoin, they both have red asterisk because of unresolved scam accusations, but they are still listed here. This thread is simply an overview of all the signature campaigns.
Alert canceled, we have update:
Sorry for delay, we have received too many applications for our campaign...
We are ready to use escrow...
At the moment our campaign is FULL...
There you go.
