why do we have to clear our cookies before a survey?

[tallicadude]

i haven't done it once yet because i didn't know i was supposed to. but i haven't had a problem getting credited.....yet. the reason i ask is because i have cookies enabled for a reason, i have too many usernames and passwords to remember. plus it makes offers and surveys go a lot faster because a lot of times i can just double click in some fields(name, address, email, zip code, etc) which helps immensely when you have a physical disability like me. so what's the reason?

Also I think you have to be using IE as it seems that Firefox users never get credited.

I use firefox and I just received email that my last 2 surveys were credited. I also have cookies enabled and have not cleared them yet. I have not had any issues yet and hope not in the future. Are we required to clear cookies?

Clearing cookies hides the fact you've done the survey before, thus allowing credit possibilities
