Prevent Follow Spam

[jjeffryes]

It's possible to spam someone with follow/unfollow requests from the same user.

Ideally there would be some mechanism in place to prevent a notification if the same user follows you more than once within X minutes.

Ratcheting the delay would be nice, so you get the 2nd notification, then no more for 5 minutes, then no more after the 3rd one for 10 minutes, then no more after the 4th one for 20 minutes, doubling each time.

If that's impractical, not showing a duplicate follow notification within 1 hour seems reasonable.
