I've noticed a lot of topics being bumped recently with "BTTT" (back to the top) comments or "Marked" as the reply.
I'd appreciate if people think twice before doing this. Simply forcing topics back to the top even though there is nothing to say on them is not helpful and negates the usefulness of having an Active Topics view. If everyone did this with every topic they want to push then things would quickly deteriorate so I don't believe some should be allowed to do it for whatever reason.
By all means post new and relevent comments to a topic but short esp single-word non-comments that are simply used to push certain topics back to the top are likely to be interpreted as spam and removed or blocked if necessary.
