Just imagine, this is an old school forum, people need to get used to it before they can start to shitpost a lot...
If the UI would allow to post as simple as FB or other social media sites, there would not be possible to hire enough mods to stop the spam...
If such thing will be applied, we don't need to stake Bitcoin address, because people mostly self-disclose their identities on Facebook. They don't care about their identities can be used (abused) to steal their funds and lots of others shady things. In other words, Facebook need as many new (real) users as possible, the forum does not. What the forum need is as many quality users as possible, we don't need to see new (real) shitposters.
