"[W]e have recently increased our automated efforts to remove Likes on Pages that may have been gained by means that violate our Facebook Terms," the social network Friday.

Details about how Facebook has altered its automated efforts to purge the system of likes generated from botnets and malware were left out of the posting. No doubt, too much detail could enable miscreants to take measures to counter Facebook's efforts.

However, the social network did little--other than estimate the new system would, on average, eliminate less than 1 percent of the likes on any given page--to assure legitimate users of the system that the new automated broom used to sweep bogus likes from its pages won't create bigger problems with false positives than already exist.

"Is it because of this, that you blocked me, an honest entrepreneur 3 times (the last one for 30 days) because I was making friends?" , a pet services provider in Montreal, complains in a comment about Facebook's cleansing efforts.

"Couldn't you make the difference between me and a robot!" he adds. "Finally, when its time to talk to someone at Facebook to show that I am not a 'menace,' it was more possible to have a date with Lady Gaga than talking to a human at Facebook."
