I've been saying this for literally years (see my post below from 3 years ago), but for some reason we have done absolutely nothing to address it and Bitcoin Discussion is still a spamfest:
I gave up hoping to see some major changes some time back, I now only just read through and try to use a filter to choose what to interact with and what not to (I personally do not like the idea of ignoring a user or a board).
It's sort of ironic that as Bitcoin (the network) rises and gets more popular, bitcointalk (the chat forum), gradually declines, or at least a part of it does.
