Well, what kind of requests?
Yeah, reminds me of the issues with Mastodon hammering websites for image previews as posts circulated among instances.
I wouldn't be surprised if something of yours got boosted to a large followers list, causing every one of those instances to respond with a request to your instance, without you even knowing.
Maybe even a QT that's not being reported in a standard way back to you.
@volkris
That is a good theory, a QT of my introduction by someone that has many followers, but I would get at least one follower... I think.
