Hello.
cast.garden was initially reported as spam as it seems to be a service identical to tdvtv (Dollar Vigilante).
The service basically cross-posts content with no engagement with the community and is self-voted by the owner.
A few communities have already muted cast.garden for spamming their tags with junk posts with irrelevant content (Hive Open Mic, Cinnamon Cup Coffee, Puku Mundo).
cast.garden is not blacklisted. There will be no more downvoting from HW.
We are not responsible for downvotes from the community.
P.S. tdvtv was asked a year ago by some stakeholders to decline rewards on the posts as it was farming the rewards (although it seems that it started to farm again).
