Delete (sender's) messages

People can delete messages they sent but are not able to delete messages people sent to them. There are a lot of reasons why people should be able to delete the sender's messages. One of the reasons why people should be able to delete the other people's messages is because they are getting sent unwanted/inappropriate messages they do not want to see. Discord is not an app people can send irrelevant messages, it's an app for chatting with gamers. There is a way to delete other people's messages on Discord HOWEVER that is done by blocking the person which is ridiculous! Apparently you have to block a person because of one message you don't want to see! ONE! (Also you cannot message the person once you block them)
