If it is using synonymous is becoming quite complicated, you need to be able to identify two different words are actually the same. Peraphs as you read the sentences you should substitute words with a code wich corresponds to a subset of synonymous then use these cleaned sentences to run the checks.
Maybe there are dictionaries ready for this sort of things. In any case comparing 1 message with all the previous message running perhaps multiple check can be quite expensive to perform.

There are dictionaries and other methods to deal with synonyms but they don't work well for crypto-themed texts without a serious ML effort. Worse yet, Bitcointalk text spinning bots don't really care much if the text makes sense so they'll replace "cryptocurrency" with "financial encoding" or some bullshit like that. Semantic comparison seemed quite useless to me so far in this context though I'm not an expert by any means - just learning as I go.

there are a lot of users who use actively bounty work & majority percent bounty post almost like same. Not only that script will detect similarity percentage so bounty post approximately 60/70% similar to each others. So how could it detected this script.

Good idea, I think we should report the whole bounty board as plagiarism
