Jim, I didn't look hard, found out according to this thread that dotster was one of them:

Basically I treat .info domains the same way as I treat third level domains - many people PAY for third level domains (pair.com, example) but mostly they are free hosts and scams. So I don't list them.
I have no way to know if a .INFO domain is paid for or not, so I assume not and I work from there. As with Ramster, I am only likely to accept them from known submitters and people I have confidence in.
.INFO domains were not intended for porn, so their use in porn is questionable. I would not be surprised to see the operators of that FLD come down and make life tough, say about this time next year.
