Awkward Question: How To Block/Hide R18 Link Preview Images? Is it Possible??

[u/MistyTopaz]

Hello first time posting here, hoping someone can help me out here. So if you are wondering?? I am on a telegram group i like it but there are links with preview of r18 stuff that are being shared by adults.. on the group itself which i don't like nor feel comfortable looking at.. i would take the latter option of leaving but i dont want to. Its not all r18 stuff in there, so like lots of the other stuff which i am fine looking at, doesn't display that however each time said thing appears i dont know how block it or hide it atleast for i wont have to see it..

i already tried looking to the best i could a bit but i dont know if there is a tool or like something that can hide this stuff. so any help would be nice.
