On Twitter, users can hide replies to their posts using the "Hidden Replies" feature. This feature allows users to conceal unwanted comments under their tweets, but the hidden replies can still be accessed by viewers by pressing an icon at the bottom right corner of the tweet. To view hidden replies, users can click or tap the hidden reply icon which will be available in the bottom-right of the original post. Hidden replies are removed from the conversation, but they are not deleted, just shunted out of the way so they dont interfere with the other replies. Users can also unhide a reply by selecting the "View Hidden Replies" option. It is important to note that if a person deletes hidden tweets, they will not be visible anymore.
