I bumped oldest (not locked) thread I could find and it seems working.
We should see how this is working in a few days, when spambies realize that their weather forecast discussion won't bump threads any more.
The weather forecast discussions that took place in several threads were the lowest of the low type of bumping along with the one word posts in their fake conversations.
Got to laugh at
spambies though

So basically this will mean that the Chipmixer ANN is going to be pinned on the top of the board for... for ever?
Or really, any ANN from a company where more senior members here have a vested interest in bumping the topic..?
Maybe an unintentional side effect, but that's really a massive advantage that they'd get over other companies/etc.
Or not... I don't know.
Bitcointalk seems to become more and more of an esoteric meritocracy.. Where people with higher ranks, or those who spent more time here, now also have a more powerful voice? Hmm. (Or am i understanding this wrong?)
As much as i disliked these threads with account farmers talking to each other, i don't know if such drastic measures are warranted, or if this is the right direction for Bitcointalk to move towards to. (Although i must admit: i haven't visited the altcoin boards in a long time, if ever.)
I have some concerns too if I am reading and interpreting the OP correctly.
I am not sure if those having higher ranks should automatically be given a more powerful voice by default. There can be a mechanism in place to select users as representatives by a vote based system but this should be fair and consistent if implemented.
Scammers will always find a way around any form of censorship so that should be at the forefront of the debate.
