Well, since the spam seems to be gone, I'll continue this
conversation 
1) Can't stand blogs that are only giveaways. It
gets old!
2) Can't stand giveaways with a ton of hoops or too many
options.
3) Automatic turn-off if people require likes or follows
to enter!
4) Usually don't enter giveaways that have more than 500
entries already because I figure I have NO chance of winning
anyway.
5) Have won some great stuff through giveaways
6) Only enter giveaways that I REALLY want, not just
giveaways of stuff that I may or may not use/need.
