FORTUNE -- Students of screen display technology look forward to the testing laboratory reports of DisplayMate's Dr. Raymond M. Soneira. The one he published Thursday was particularly interesting because it compared the screen of the new Samsung Galaxy S4 with both its predecessor, the Galaxy S3, and its main competitor, the iPhone 5.
His conclusion: The OLED screen technology that he disparaged in previous Samsung Galaxy models had just about caught up to the LCD technology in Apple's (AAPL) co-called Retina displays. In his latest report card, the Galaxy S3 got a B+ and the Galaxy S4 and iPhone 5 both got As.
Fair enough. Kudos to Samsung.
But a funny thing happened when the results got reported on Twitter. Identical tweets were posted over and over again -- not retweeted, reposted -- under different accounts.
Two versions caught our eye:
Not only were they posted two dozen times between them, but judging from the photos attached to the accounts (see above), they were posted by some particularly comely tweeters.
"This is not a bunch of fans just bragging about their great device," suggests the reader who spotted the repeats. "I'm gonna guess this is somehow Sammy's PR shop."
UPDATE: Dr. Soneira did the research I should have done and concluded that Samsung PR is probably blameless on this one:
"How many total tweets are we talking about? Looks like a small fraction of the total. There are over 600 tweets regarding my article, plus Google shows about 6,000 articles and blog hits covering the article. So these tweets that you mention are insignificant from my perspective.
"I looked up the tweets that you referenced ... and they all point to phonearena.com, so it is rather obvious that they are the ones arranging the tweets to generate traffic to their site. You also referenced gsmarena.com. Both of these "arena" websites sell Smartphones, so it is again obvious that they are driving traffic to their websites to sell Smartphones and they write short blog pieces (covering articles like mine) to help them do so. That is the source, not what you speculated..."
Mark Zuckerberg's fan page was hacked, scams permeate the news feed, and fake profiles abound. What's Facebook doing about it?
Objections over privacy, or the lack of it, have plagued Facebook for almost as long as it's been around, but only recently has the social network's security become a contentious issue.

Spam sites are mostly benefiting from Adsense advertising...and so is Google.
Today, Google's (GOOG) Matt Cutts blogged that they were aware of the recent complaints about spammy search results and were taking actions to correct them. But complaints aren't just that Google is showing spammy sites in the search results. There is concern that the reason those spam sites are showing up higher than the original content they are reproducing is MORESeth Weintraub - Jan 21, 2011 3:46 PM ET
