Do mods have the power to shadow ban? If not, my problem is not with them (you) but with the admins (i.e. paid staff rather than volunteers). In any case whether it is admins only or mods and admins given this power, regardless of how non-corrupt an individual may be, shadow banning is a corrupt practice. True, I should have spoken out about it before it affected me and I regret not doing that. I hope there is not a similar sneaky, underhanded rule in effect here.
The philosophy of Hubski is to let users control their own experience, by following users and tags. Also, there are mechanisms to avoid users you may find distasteful (ignore, mute, hush, for example; see the primer page for details). With these mechanisms, it has never been necessary to ban anyone thus far (and shadowbanning doesn't currently exist here).
1. Nope. No power to shadow ban or remove it. Nor are we ever informed that it has happened, nor why. Usually a user complains that they can't see their stuff, we check, and give them some links to approach the admins 2. Most shadow bans seem to be via algorithm (not human action). And admin do appear to fix erroneous instances. So not really "corrupt" etc there either. Bear in kind that admins have also created a special sub for help/info on shadow banning, where the shadow banned can still post and be seen.
