I posted a video last week and the comment was "nice writeup" -_-
We definitely need to do something about this. We don't want newcomers to come here and see this place as spamland. We don't want them to think that it's the right way to be good at Steemit too.
Even if/when comments like that aren't spam - which surely is sometimes the case - it's really not adding much anything of value to the dialogue.
Maybe it's just my personal opinion, but why comment anything at all if it doesn't say something more than such a generic acknowledgement. Why is it a nice writeup? What about it do they like? What did they takeaway from it? Etc...
Perspectives like those might add something worthwhile to a dialogue and enrich the flow within the community...
