I find this quite interesting - is it common for publications/websites to have Telegram channels now? Is this to use it as an RSS reader?
It's common in countries where Telegram is popular.
What bot are you using? The ones I tried quickly became unbearable because of annoying ads.
I've recently written a basic telegram bot. It really is quite trivial; could be easily done via a bash script calling cURL and installed as a cron job.
