Twitter says spam levels have dropped significantly to a new low of 1 percent of all tweets. Spammy tweets averaged in the 5 to 6 percent range most of last year, but started to dwindle in the fall. Twitter has a “report for spam” link on Twitter profile pages, which alerts Twitter about a sketchy account and blocks it from following or replying to the user who reports it. Twitter earlier this month added a new service that detects malicious URLs before they hit the feed.”]
