The investigator said ads shown to subscribers create security risks and hurt user experience, while Telegram Premium users can boost the channel toward the threshold needed to turn ads off.
ZachXBT said Telegram is still allowing scam ads to appear to subscribers in his channel, describing the placements as a security risk and a drag on user experience. He added that Telegram Premium users can use the channel Boost feature to help the channel reach Level 50, the threshold required to unlock the option to disable ads. The complaint highlights a moderation and product-design issue on Telegram, where creators may need enough paid user support to access controls that limit potentially harmful advertising.
