If you cant access channel
IF YOU CANT ACCESS MAIN CHANNEL FOLLOW THESE STEPS: If you are on iOS (apple device) & can’t access the channels, or live in a country that bans xxx try this:
1. Login to your telegram account at telegrams website ( web.telegram.org )
2. Tap the 3 lines and Open settings > privacy and security
3. Check and turn on the setting Disable filtering under sensitive content.
4. Delete & reinstall telegram app on your phone or computer then log in and try to join again.
5. Here is a video showing the steps you need to take in order: https://www.youtube.com/watch?v=M_cV7PcIIgQ
6. On Ios (apple) you may not be able to see previous uploads if the above steps dont work. You however, can click on the channel name at the top and view the media/links to access the folders in the links section. A trick is to also forward or share the posts you see with emoji reactions to your saved messages. You will be able to see the nsfw preview pic as well as the link below it.
Possible alternate methods if the above doesn't work:
1. Try some alternative Telegram apps then try to join the link(Telegram Lite, Nicegram, BGram etc - there are many choices)
2. Get the Telegram apk directly from the website, not the Play Store (android only)
3. ( only If your country doesn't allow xxx) Create a new account with a US number using 2nd number app (Talkatone, TextNow, Burner etc - set up 2FA asap)
4. Set your account to be deleted after a year in your settings (the longest option) Telegram WILL delete your account if you dont open the app every once and a while.
Still not able to access main channel? then join SFW channels. All links and uploads are there as well.
