It's a good thing I'm seeing this now, considering the fact that I'm still new and trying to be at home here.
Well tag abuse should not be promoted, but what about when a post is relevant to multi front ends? A user might make a post which is relevant to #leofinance, #pyb and #vyb, and many other front ends. The motive might not be for the token, but for visibility and engagements of people around.
Perhaps It can go well if we can have a clear definition of post that can carry #vyb and #pob tag, so when unrelated post are carrying the tags, action might be taken against such user.
