Hey Newport,
Although I’m not totally sure, I believe the answer to your question is if you enter via a website that you pay a subscription to automatically enter a sweep, that would be void.
These sites use software to go to the site and automatically enter the required information. That’s why a lot of sweeps sites require you to enter a code using letters, numbers, etc. Concerning using Roboform, autofill, copy and paste, unless the rules specifically state “manual entry”, “typed entry” or such, you’re free to use Roboform.
I do and I’ve won stuff, small things such as Red Robin gift card, bottle of wine, Throw rug, set of lotions from Nivea and I’ve only been using Mr Sweepy for three months. I’m hoping to win a car so my roommate will stop borrowing my car LOL.
Because there are tons of other sweepstake sites, remember that your chances of winning big is not so assured but can be done as others on this site have proofed.
Be thankful for your luck but don’t rely on it. :o)
