Thanks for the reply. I suppose there's no harm in me speaking to them about it although I am currently a small site so they probably wouldn't be interested.
If I had appropriate spam protection would that help? Some of these sites are survey/market research sites and they survive on getting plenty of users so I thought they would want to assist website owners with helping people sign up to them. The average person who signs up to these sites usually wants to register with a few different ones anyway.
