Chalk up a win for Facebook in the war against malware and spam: The two companies extinguished further repostings of bogus $50 gift cards for Starbucks.

These posts were going up at a rapid pace until around 5 pm Eastern Standard Time.

Now technology from Websense and Web of Trust stops the repostings with a warning message.

The warning says that Facebook is blocking the web address Bestgiftalert.com for being “spammy or unsafe.”

The message also provides a link to the social network’s help center.

There’s also an alternative for people who believe they’re seeing the pop-up window in error.

The swiftness of this techonological response seems very promising for security on the site.

Readers, did you see any posts about free $50 Starbucks gift cards on Facebook before the site started blocking the web address involved?
