I've dropped a few warnings and flags in the oasis, almost exclusively for using wrong tags. I don't want to see actifit on steemleo.
On a post I gave a warning, leocurator flagged the post for the same reason. I don't think there as obvious tag abuse on steem/palnet, and spam/plagarisiam/100% selfie maximisers are more the issue.
Agree fully with this being the user acquisition phase, people are adding value by just being here - most of them.
