I think this is not about fighting spam, or abuse. The amount of social control that is created by tying online accounts to your person is staggering. Requiring a phone number, then a photo, or ID, is something that we only saw in China until recently. Now it got introduced through the backdoor in the West, too.

The other day, somebody here in Germany got visited by the police and had their phone confiscated because they "liked" a (admittedly nasty) tweet on Twitter. I firmly believe this has a chilling effect on society and we need an unsupervised space for free speech.
