Can confirm that the hashtag doesn't work, though obviously we don't know if it has been 'banned'. Other hashtags work fine, even 'telergam'. In fact, if you search for 'NONEXISTENTSTRING OR #telegram', you will get the results for the hashtag itself - suggests a manual banning.
Like u/Lurker404 says, it works perfectly fine without the hashtag.
