Well, there are a few people out there that take sweeping to an extreme and resort to cheating. Camel did a great job of eliminating the multiple accounts and limited instant wins to one per account.
2. Please allow for autofill. Some sweeps do not allow auto-fill and not only is it tedious for daily entries, it can lead to TYPOS and then you never get your prize because of a TYPO.
3. I know this will not fly, but I hate the social media sharing for extra entries deal.
4. Lately, I feel E-prize is banning sweepers from winning. I could be wrong, but if they are doing this, this is wrong.
