Which Way to the "Seller's Forum"

[RealToppsaholic]

where do the sellers gather to list all the jerko buyers ?

seems like a lot of 'buyers' here complaining about sellers and their items -
from PWCC retractions to fake psa cards, ebay conspiracy theories to fake signature videos, people being 'outed' for nonsense ...

but where do the sellers list problem buyers and blocked lists etc ?
where do we list those who mis-use return policy, steal items, complain and/or write rude messages, retract bids, etc --
I could use a 30 hour-per-week employee just to write to all the clowns with silly questions etc

what an industry...err I mean hobby.
