Every sweepstakes has their own rules, that they must follow, in order to comply with the laws regarding sweepstakes in their state.
I have never heard of an entry being refused because it originated from this site. *Some* sweepstakes rules prohibit automated entries - those ones that are made by sweepstakes subscription services, which use computer programs to go out & enter sweepstakes for people who pay them a fee to do so. But, that's not what Sweepstakes Today is. Sweepstakes Today is just a website that compiles sweepstakes entry info so that it's users can *manually* enter the sweepstakes themselves.
