Miriam Ezagui, a TikTok creator and nurse with 1.9 million followers, said some popular editing features on the site were being used by some users to twist her words in a video and send waves of hatred her way.
Mr. Presser said the use of the tools to perpetuate hate was another “important flag” for the company to follow up on.
“We can do better,” he said.
Ms. Messing, who has more than 37,000 followers on TikTok, pressed executives on TikTok’s moderation of the pro-Palestinian slogan “from the river to the sea,” which many Americans regard as a call to eradicate Israel. It has been deemed antisemitic by the Anti-Defamation League and has appeared in messages and comments to many Jewish TikTok users, regardless of what they’re posting.
Mr. Presser said the phrase was up for interpretation by TikTok’s 40,000 moderators.
“Where it is clear exactly what they mean — ‘kill the Jews, eradicate the state of Israel’ — that content is violative and we take it down,” he told the group. “Our approach up until Oct. 7, continuing to today, has been that for instances where people use the phrase where it’s not clear, where someone is just using it casually, then that has been considered acceptable speech.”
The notion of the term being used “casually” upset several participants.
Ms. Messing asked the company to reconsider its stance, saying: “It is much more responsible to bar it at this juncture than to say, ‘Oh, well, some people, they use it in a different way than it actually was created to mean.’ I understand that you are in a very, very difficult and complicated place, but you also are the main platform for the dissemination of Jew hate.”
