Yes I do 3D, whenever I post a image which isn't all that often now a days but in fact I just posted one today and have recieved a number of notifications of replies without any spam coming in.

I'm honestly at a bit of a loss to explain it on my end.  I tried to think if I personally was doing anything different in terms of sites I was going to, corrispondance, security upgrades, etc. and also since this is not an exclusive one-user computer I asked around a bit as well but no one has been doing anything different that they can recall.

The only thing I can think of is that I'm not purchasing as much as I was for a few months, but only one of those purchases was a Renderosity product anyways so I don't think it's related and as I mentioned I used my freebie gift certificate the other day with no ill effect spam wise.

Sorry I can't be of more help....
