Bitly added a verification process, @Bitly reminded followers on Monday evening, linking to a June 30 bitly blog post titled “Introducing 2-Step Verification for All Users.”

In an emailed response to Target Marketing‘s request for comment, Bitly states:

Bitly has been on and off of Spamhaus’ list at any given time. There’s a number of reasons that an open platform like ours can be captured as spam—but Bitly proactively manages abuse through a combination of manual monitoring and management, programmatic detection and through relationships with external security teams.

Bitly continues to develop security and abuse protection-oriented systems and features to combat inappropriate use of the platform. We recommend third-party integrations adhere to our published best practices and all users should report spam whenever they encounter it.

Google didn’t immediately reply to emails on Tuesday requesting comment about being on the Spamhaus blacklist.
