Here's a partial quote of what I wrote about bumping services in a meta thread:
What if the ANN thread is self-moderated by the OP? If the OP is not actively pruning shitposts after, say, 24 hours, then it seems reasonable to conclude this is not a case of a competitor attempting to tar the competition.
EDIT - for example, here is a rather egregious violator:
the Roomdao ANN thread.This is a self-moderated thread that is seeing a new post every 2-3 minutes on average, and virtually none of those 3400+ posts is worth a crap. Thus, we can safely conclude that this is not a competitor trying to frame Roomdao for incentivizing posting to its ANN.
...
Note who I used as an example...
I stand by my assertion that if the topic is self-moderated and there are *hundreds of pages* of spammy replies, well, the blame lies squarely with the OP.
