you don't have to wish them all good luck, i made the same mistake in my first giveaways
most of them are using an autojoiner with a script that writes thank you in each giveaway they enter, quite a nuisance in my opinion and that's why it's important to set level restrictions
that's also the reasons why no one answered you

and with all your public giveaways i think you qualify for Amanos whitelist, if you're interested:
