I actually don’t see any need why the forum should start censoring post just because they included a curse word in it, if you don’t like the way an user responded to your post the best thing you can do is to ignore them and forget something ever happened rather than to start engaging in a heated argument with both of you insulting yourself, after all you don’t know them and they don’t know you, so don’t let anyone’s words get to your head.
Don’t forget that this is a forum and everyone should be able to give his or her own opinion without being censored. And once the content of user get removed because of their choice of words then that would defeat the whole idea of “freedom of speech”.
No one actually has freedom of speech because at some point you have to follow the rules of the platform that you are using to convey your message. For example, if you make some advertising, a CTA message, or a post in a Bitcoin discussion, that topic will be moved to service discussions, which means you have no control. Another example is if you make a post with some faulty or wrong information and try to lead people the wrong way, you will be tagged as neutral or maybe removed if you are found guilty of plagiarism. We all know that by following the simple rules, we can live forever here until we die, but if we don't follow the rules, we can't survive here.
Now, if we talk about abusive language, then use of foul language is not encouraged here; instead, it is banned here, and the best way to report such pist is to report it to moderators, as, in my opinion, censor filtration tool integration is not going to help. As many members tried to emphasise, do not use filtration as it will only cover more space on the domain or hosting while we have moderators who are getting paid and have the full authority to remove someone's post if they are not following the rules.
They will not alter the post, which means they will not edit it, but they could delete it.
