Sounds like a good idea to me. Let Users have a Block mechanism towards the Memos section and Spam there.
It seems like it is really getting worse and worse from when I first started here in December with the Memo Spam.
The Resteem services are pretty much garbage. People building up HUGE Following thru Robots or excessive "you Follow me I Follow you" campaigns.
Its a waste of SBD, imho.
Thanks for this Post @drakos
