Off topic discussion is welcomed by me but IMO what (I believe) is being discussed here could be defined as having become spam. What starts as venting or opinion sometimes ends up as a sustained campaign. The term "political soapbox" springs to mind.
One or two threads on a subject isn't a problem at all. New threads (many with obscure names) popping up constantly makes it harder to navigate and blurs the focus.
eg some people don't like "babe" threads but if there's one and it's called "babes" people don't care, it's not particularly invasive. Fourteen threads called variously "Curves on a GT", "Rear end shots", "quarter vents" etc, all containing "babe" content, might be seen differently even if the total number of "babe" pic's is similar.
Personally I think a forum should have reasonable gravity toward focus. Plenty of outlying discussion sure, but IMO the level of the political tirade over the last year has been skewing the focus. Signal to noise, which used to be fantastic here, is now average. If that doesn't constitute abuse then it is at least a shame.
There are places relevant to almost any subject all over the web, why does this forum have to be diluted without let up?
I don't believe freedom of speech and censorship are the issue here. I believe that freedom of choice is being limited - sure we can pick and choose threads but at a higher level we already pick and choose our forums:-
I wouldn't go to the opera and expect a fight to break out in the crowd, similarly I wouldn't go to a boxing match and expect the place to break out into a chorus from La Traviata. Both situations would be disruptive, and although certainly entertaining in the short term, if it continued to happen every time I visited it would make my choices difficult and unclear.
Defining reasonable and relevant will always be a headache - people have varied opinions. IMHO you've done well so far and anyway, it's your forum. I'm happy to go with whatever happens.
I voted to index. To some extent I guess I'm playing devils advocate but I do think there are valid points on both sides and that things are a bit unbalanced ATM.
Common sense can be argued from both sides IMO.
I commented here because I had PM'd you regarding a similar discussion happening in a thread at one point a while ago and you stated that you'd brought this up now because of PM's.
Mountains and molehills...
