Donald Trump announced he would participate in a Reddit “AMA” Wednesday night, opening himself up to questions from users — but under restricted terms.

“For this AMA we have temporarily taken extra security measures to keep our community free from troublemakers. We built the wall 10 ft taller, you might say,” a Reddit moderator wrote on the thread.

Among the conditions, the Reddit thread would not allow new users to submit questions.

“Trump’s AMA is not like most AMAs. Pro-Trump mods are screening q’s, only allowing established supporters to participate,” Benjy Sarlin, a political reporter at MSNBC, tweeted.

Some criticized the censorship of Trump’s thread. “The Donald Trump Reddit, bastion of fighting political correctness, is a literal safe space. Can’t make it up,” one user wrote on Twitter.
