An email to Telegram

Hello

I'm writing this email to inform you that the channel

https://t.me/ha**asael_m**at

with username "@ha**asael_m**at" is infringing on my copyright. I'm a math professor and I sell the pdf file of my pamphlets online in my weblog "www.riyaazi.blogsky.com". The address of my weblog and my phone number "09103854562" (in persian format   " ۰۹۱۰۳۸۵۴۵۶۲ ") are watermarked in all pdf files.  I asked the owner of the channel to remove these files

https://t.me/ha**asael_m**at/36

https://t.me/ha**asael_m**at/37

https://t.me/ha**asael_m**at/38

but he/she refused. The abovementioned links include a low quality version of my files in which my weblog address and my phone number are discernable. To prove my ownership, I have attached the first pages of my files (in original quality) and I have posted this email in my weblog in the following page:

All the other files in the abovementioned channel are copyrighted books. For example the file

Is published by publishers like this:

Although  I don't have the ownership of the other files,  but I recommend you to ban the channel because of copyright issues.

Best regards
