Reddit CEO Steve Huffman has not only issued a formal apology on the social media platform for editing comments made about him on the site by Donald Trump supporters, but he's announced a big change to the site as well.

In a long post on r/announcements, Huffman begins by saying, "tl;dr: I fucked up. I ruined Thanksgiving. I’m sorry. I won’t do it again."

Perhaps the biggest news, though, is buried in Huffman's PS: There's now filtering available on the popular r/all. Huffman shared a video (below) on how users can filter out subreddits from their personal r/all page.

The action can only be taken on the desktop version, but Huffman says the filtering will apply to a user's account on all devices.

Huffman also addresses his actions (which resulted in some angry users calling on him to resign), going through his own history and his thinking about why he edited the comments and why he was wrong to do so:

While many users across the site found what I did funny, or appreciated that I was standing up to the bullies (I received plenty of support from users of r/the_donald), many others did not. I understand what I did has greater implications than my relationship with one community, and it is fair to raise the question of whether this erodes trust in Reddit.

Huffman also announced other changes, as well. Stickied posts from r/the_donald will no longer appear on the r/all page. In addition, new actions taken in regards to the r/the_donald subreddit, where the controversy started. Moderators are taking action against the subreddit's "most toxic users" which ranges "from warnings to timeouts to permanent bans."
