Redditors are collecting the blacklisted sites at a freshly minted subreddit, r/BannedDomains. The list so far includes at least five: BusinessWeek.com, Phys.org, ScienceDaily.com, TheAtlantic.com, and GlobalPost.
This mean that Redditors are prevented from submitting links to any of the above sites. Instead, they're greeted with the following message: "This domain has been banned for spamming and/or cheating."
The move comes exactly one week after Reddit announced a new site-wide ban feature intended to cut back on spam. However, the official announcement noted that only URL shorteners, commonly used by spammers to mask destination links, would suffer initially.
"Some domains are not allowed on any part of Reddit because they are spammy, malicious or involved in cheating shenanigans. Attempting to submit a link to one of these domains will now fail with an informative error message."
