Please Explain.

AES is an abbreviation for "Advanced Encryption Standard", which is a designation given to the cryptography algorithm nominated in 2001. Yes, it's in use by the US government and just about everywhere else. AES is used to secure your mobile device's storage by encrypting it, it encrypts internet communications, files and the list extends further and further. Simply put, AES is the gold standard of symmetric-key encryption.

That however probably doesn't have anything to do with the bot you're being pressured to add. For one, you should never add untrusted bots. With permissions above an average visitor, a bot can do just about anything with your server. Delete it, spam NSFW, change it to the way the user wants to or to perform other destructive tasks, which is actually now a common trend and why you should never give permissions to any bot which you haven't confirmed as safe. Even if you do not give it permissions, it can still be used to collect data, log messages and so forth, possibly being used against you in terms of privacy.

If you have limited information about the bot or it is untrusted (such as in this case) then I highly discourage you from giving it permissions in your server, let alone even inviting it. It's more likely than not that the person just wants to get elevated permissions in your server then destroy it.

@63456Ok thank you for the paragraph of info really helped.
