I'd be more okay with the idea of these lazy giveaway posts, if they took the rewards they made from said post and then gave it away in a following giveaway and just kept pooling it up every week for bigger giveaways. I don't think there's really anything wrong with doing the leave a comment and I'll pick a winner thing. So long as you're not profiting off it and you're working towards doing bigger and better giveaways. Kind of like a scuffed, dollar store brand Mr. Beast.
Otherwise, I agree, this does just seem very reminiscent of the good old bot vote farming days of Steem. I think your suggestion of doing something different is fine, but lets be real. 99.9 percent of these people are soulless husk zombies looking to suck up as much money as they can. Otherwise, most of these people would have started out doing something more unique, as it's really not that hard.
