One of the big trim problems of Aternos

The biggest problem with Aternos is that we can't upload plugins or files ourselves. Well, it is true that these files may have malicious code, so how is this possible on sites like "Server pro" or "Minehut"? We may not be able to upload plugins, which is not a big problem, but plugins like Scorehud, which is one of the most important and useful Scoreboard plugins, need Addon. I know that this issue has been tested many times before and you told us to use the old versions, but when we do this, the server crashes and says that the plugin should be updated to the latest version, but there is another way. I'm currently using it. First we have to change all the plugins that support Scorehud to their old version so that the server does not crash, but again this problem is not solved because we can not use the old versions of plugins forever I want to know why you do not address this issue. And you behave in such a way that there is no problem at all.
