The purpose of this thread is to warn of what may happen if more restrictions on signatures are imposed, not simply to rejoice in looking at a still photo of what this forum looks like today.
I doubt that theymos is not aware of the fact that bitcointalk owes vast majority of its current traffic to signature campaigns so I don't thnk that he will easily impose any further signature campaign restrictions. Mixer ban coulnd't be an easy one either and imho it was obvious that it was just a matter of time.
The thing is, the forum doesn't need traffic to survive. He's stated a few times over the years that the forum is doing quite well financially & doesn't need to raise money for anything. He's also stated that he thinks its cool that people can earn money from posting. I'd be very surprised if he announces any more kinds of signature bans.
And that's one thing that can't change, right? Motorola and Nokia also had a great reputation and prestige.
Bitcointalk isn't a company. It's not operated for the sake of accruing a profit and doesn't require revenue to continue existing; at least not for decades, or maybe even longer.
