I've not seen that. Just had a quick look, but there's a lot to digest. People always talk about bullying with downvotes, but that is a minority sport really. It tends to be those who got caught out abusing who complain the loudest. With things like SFR most people did not see all the good it did by removing rewards from crap posts.
I drop in on Blurt now and again, but there is not much happening apart from people milking it. That is not really interesting to me. I can see that they are trying to reduce abuse by charging for everything, but it seems there is profit to be made by 'circle jerking'. I did have some account leave a load of empty comments on my post, but I can't see how they benefit from that. There are people posting the same stuff there, on Steem and here to cash in.
A lot of trending Blurt posts have no comments. So much for engagement. I am happy with the activity I see on Hive in general.
