Twitter Locking Accounts Question

I am running 100+ Twitter accounts on Followliker and yesterday I checked them out and about 10 or so were make as LOCKED.

I went to sign into those accounts but they didn't have any message from Twitter about being locked. The strange thing is that the accounts were still lrunning but only hitting about half of their daily limits. What's going on here, anyone have any idea?

twitter announced today the roll out of a new spam and offensive posts filter/block it will block all offensive posts and suspicious accounts. heard this on the radio news here in Ireland today. It will probably cause problems for many I.M. accounts

The new filtering feature is targeted toward a problem that has plagued Twitter and Twitter users for years, a fact acknowledged by the company's CEO. Earlier this month, internal company memos obtained by The Verge quoted Twitter chief Dick Costollo as saying that "we suck at dealing with abuse and trolls on the platform and we've sucked at it for years. It's no secret and the rest of the world talks about it every day. We lose core user after core user by not addressing simple trolling issues that they face every day."

Twitter have probably caught some of your accounts out and are in the process of stopping them from working.

What were you doing on those accounts OP?
