My time is valuable - especially my free time, which is when I am a able to browse Bitcointalk. I refuse to waste hours of that time searching through pages and pages of spam for the one or two comments that include an original or well-articulated though. As I mentioned before, finding threads early can sometimes lead to a good discussion over a couple of posts, but as soon as the spammers take over, I usually give up and remove the topic from my watchlist.
Unfortunately, its not going to get better without people reporting it. It doesn't mean that we are relying on you to report alone. More people in general need to be reporting. I'm a patroller, and I don't seem to get that many reports in the Bitcoin Discussion section. Maybe, there's not that many newbie spammers there, but I would think they are a big portion of it.
The forum has got so bad that probably 90% of posts in Bitcoin Discussion threads are spam or unsubstantial so reporting is futile and it would be a full time job trying to report all the posts that actually need to be removed. Ain't nobody got time for that. Without changes to what is actually allowed to go on here then nothing will change. A handful of users will still keep reporting for whatever reason but it's like picking one turd out of a sea of shit. Signatures from lower ranks need to be removed and badly run ICO campaigns need to face repercussions for shitting up the forum.
