A guy gets sent to hell. The demons guide him into the lobby. Satan jumps out and lets out a big evil roar to no effect. Satan then glances down and sees the spot on the mans finger where there was a ring. "Oh... well you've been through worse. The break room is down the hallway to the left, mail room is upstairs to the right..." Satan just walks away.

Every step is optional of course. There are ways to make curl work on my site but I choose to add friction as some botters abuse libcurl. I doubt anyone else will do what I do. They could spoof the user-agent but most botters seem to not know how to do that despite the myth that they all do.

For what it's worth if I had a site specific to sharing code artifacts or archives I would not block curl and I would also enable native rsyncd.
