I am running cryptpad.at
Some time ago I asked for listing my instance publicly but was told CryptPad does not support instances in the form of cryptpad.TLD
I had my reasons to use this domain and have yet to implement a better solution (e.g. founding an NGO).
I was surprised that while looking today at the docs for something unrelated, this policy has not been documented yet.
Which is a pity, because I read the docs very carefully back then and couldn't find anything concerning one shouldn't use cryptpad.TLD
I kindly ask you to update the docs or revisit the policy.
PS: I was today looking at https://docs.cryptpad.org/en/admin_guide/admin_panel.html#admin-list-public, https://github.com/cryptpad/cryptpad/blob/main/CODE_OF_CONDUCT.md and https://docs.cryptpad.org/en/admin_guide/installation.html#admin-domain-config
