This domain redirects to peepsurf.com which is a proxy. Since the url being atempted was one that spammers hit I suspect they were trying to get by my blocks. I don't know why the spam never gets posted even when they get past the block. Lammers....
I tested this proxy by taking it to the bot trap and got this.
18.104.22.168 199.210-193-49.idc-colo.qala.com.sg It passed my useragent.
I can not tell where they got the nodomaintransfer21.com from it did not come from that proxy must be running more than one both need to be banned.
