so my main concern is why bitcoin talk forum don't have a like button ( up vote ) ? that will solve lot of problems and reduce spam
And be like the other shitty forums around the internet where people keep on begging for likes, up votes, reps, etc? No thanks. It's quite different here but things are improving and in a different manner. I don't want to see the forum spammed with,
"If this helped you, don't forget to like or +rep"
"+rep to view this thread"
"don't be a freeloader like or +rep"
and all those other bs other forums have.
Another thing about other forums I've been on, they have a minimum post or worse reps or likes to be able to post in particular sections of the forum. Where's the freedom in that? Here, you can post anywhere you like even if you just created your account without restrictions aside from some time restriction that won't allow a new account to post or PM successively.
