Don't forget to do it from time to time. Telegram deletes accounts unexpectedly, without prior notice.
๐Ÿ‘36๐Ÿ‘1๐Ÿ‘Œ1
For the last 24 hours I have been receiving news about Telegram deleting accounts with the word osint in their names (for example, osintambition and dozens of others, popular and not so popular).

1. If you were an admin of one of such channels, write in the comments about your future plans (backup channels, accounts on other platforms). For those who will read the comments to remind to check all links in TG before clicking on them.
2. If you notice that some channels of interest to you are missing from your subscriptions, write a request to return the channels to Telegram tech support bots @PressBot @AmeliaTearheart @BotSupport
3. Any channel (even those not related to cybersecurity at all) can be deleted at any time. Back up your posts, copy them to other platforms. For example, Mastodon. You can find me there too: https://infosec.exchange/@cyb_detective
