lol....i think the mods are trying something new. Whenever someone follows you or your list they add it up with the previous numbers of followers & show it to you in a single notification instead of the separate notification they used to show. I used to get really surprised when 1st saw it like that. But i am getting used to it (〜 ̄△ ̄)〜
According to my stats, I just received 50 followers today, so I guess when they show up I will be doing great! ;-D In the meantime, I will just have to put up with doing semi-great. Like 2 or 3 on a scale of feeling greatness, instead of 50, which, since it's all great, is just fine. Or something like that.
hahaha....you wrote exactly how i felt the 1st time i saw notification of 10 people following my list & then later found out it was only 1. Mangago just automatically added the last 9 and showed it to me, like a kid pulling a prank Σ(  ̄□ ̄||)
For me it started happening for about a week/little less than a week now. Yours might have started from a bit earlier may be? as your account is older than mine. I am just assuming all this though.
Has anybody else's numbers gone completely haywire? If the notifications I've received lately were even close to real, I would be swimming in followers today instead of welcoming a couple. (Not that I'm complaining. A "Hi, how are ya!" is still a "Hi, how are ya!")
