That's to say: Sometimes streamers censor illogical words like "shield" and "spoiler", or even more and more illogical words, and to the person sending the message it doesn't show it replaced with "***", which leads to some communication issues.

Solution: have it show replaced for the sender as well, maybe even inform them which word it is (in case it was not a globally blacklisted word for obvious reasons). Or allow viewers to disable the censorship overall on their side if they want, just like how we have chat filters.
