Because some of them are basically crap?
Think I may have posted to that thread...
so, perhaps I am partially responsible for its deletion (if my post(s) didn't pass the crap test).
I've been posting here for 20+ years (search for my early posts - same moniker) and A'Gon has gone through several forum cleansing acts, including shutting down the forums @ one point as far as I recall and to the best of my knowledge.
Shills have always been active here, as they have been in most/all of the audio forums I've frequented over the past 20+ years.
I've found forum moderation here (A'Gon) to be quite moderate in comparison to other forums.
It's their private site and "freedom of speech" does not apply - period.
A'Gon and DIY Audio are currently my favorite Audio chatrooms.
Used to really like Audioasylum, but burned my bridge there due to political and morality issues I had with the owner and one of his moderators.
One of the mods @ Audioasylum refused to remove unsavory posts about usage of a DateRape drug and even "chuckled" @ those posts.
