@eapl.me@eapl.me The only reliable way to let the other party know is to write an e-mail or any other out of bounds communication mechansim. There’s just the User-Agent header in the discoverability extension of Twtxt itself that comes close: https://twtxt.readthedocs.io/en/latest/user/discoverability.html But it requires feed operators to actually play along and check. Active pushes are prone to spam, so I actually view the lack thereof as a good thing.
