So Twitter has taken the spam hammer to our friends/follower list and given them a good clean up, this means you may of seen a drop in followers being counted on your profile page.

Twitter had this to say on the Twitter Blog:

For some time, the follower and following counts we display have been incorrect for some folks. We’re soon to push a change that will address this issue. This means that the count you see in your sidebar should match what you see on your follower and following pages.

However, a consequence of this change is that follower counts will drop for some people. In particular, those with large followings may see significant changes as we correct for spam accounts and data inconsistencies. No legitimate followings should be affected—we’re just cleaning up artifacts in the system.

Everyone is reporting different levels of drops from under 20 to well over 5000! Seems the bigger your following the more you are likely to loose. So far this hasn't effected non-profits in any significant way but Twitter may only be part way through the clean up.

Let me know in the comments below if you have seen a drop in followers, Here is to spam free followers from now on.
