Hey everyone,

I'm an intermediate user of ASP.net working on a new 'link directory' type site.  I'd like to allow users to rate them using a typical jQuery star rating system without having to log in.  However, I'd also like to prevent users from spamming the heck out of the system.

I feel that if I had some identification for each user, I could regulate their interaction with the system.  I'd use the Cache object, but that could easily be cleared to circumvent the system- right?  Has anyone else tried to do this before? Will I have to implement logins and registration?

Mr. Bluesummers:

Will I have to implement logins and registration?

That's probably the most bullet proof way. The other is a simple cookie, once they rate an item, say it's rated in a cookie that stops them from rating it again. This does have the drawback of they could simply clear the cookies, however it will still probably mitigate a large amount of spam. This might be the simplest approach, it might be worth seeing if that is effective enough. If not, then upgrade to a full blown registration system.
