Was doing the usual tweet, follow, comment, routines for sweepstakes and got a new message when I tried to retweet. "We do not accept entries from "throwaway" accounts." Never saw that one before. Went ahead and entered all the other ways and then went back to it and retried to retweet and it was accepted. On a different note, King Sumo constantly kicks me out if I enter more than one or two different sweepstakes. "Too many entries". Then I am unable to enter again for awhile. Have emailed them and customer service said it is hard for their system to determine if I am a real person or a bot if I enter too many sweepstakes or enter them too quickly. Just a friendly FYI.
