I agree. I think there is a real risk in removing anonymity from these platforms. We do have to remember that they are global platforms. Protecting the identity of individuals in countries where there is less freedom of speech and less protection against violations of human rights.... People rely on anonymity on these platforms to communicate, to deliberate and to organize protests.
I could relate this to Twitter's little verified accounts. If, say, accounts were verified as being those of a real person, that could make fake accounts even more powerful, because they have now passed that filter and people will tend to trust those sources more. They could actually be more effective at spreading disinformation.
