Underscore in Alias leads to 404

[honze-net]

Description

When trying to edit a blog with an underscore in its name it results in a 404.

Steps to reproduce

1. I created a blog (https://infosec.press/honze_net/) and it assigned my handle.
2. Clicking on customize will let me add a description for example.
3. Clicking on "Save changes" will result in a 404. (https://infosec.press/api/collections/honze_net)

Other blogs created manually without an underscore are not affected and are working.
Creating a new blog with an underscore will lead to an error message, that says: Collection alias isn't valid.
This is a perfectly fine choice. But the first blog was created automatically and I had no idea this would happen. (I suspect that a validity check is missing while creating the user and the first blog.)

Expected behavior

Blogs with an underscore should be editable or not created at all. I guess all valid characters from fediverse handles should be valid blog name characters, but it has not to be that way.

Application configuration

• Single mode or Multi-user mode? multi
• Database? [mysql/sqlite] no idea
• Open registration? [yes/no] yes
• Federation enabled? [yes/no] i guess

Thank you for your time!

Thanks for reporting this! Yes, it sounds like an issue with whatever method you used to create that first user. I assume it was done with the writefreely config start command? Or was it something else?
