Getting pings that aren't mine.

I'm a member of a support discord that helps gamers mod GTA 5 as it pertains to LSPD:FR.  Here's the thing, it isn't confined to that discord.  It's across all the servers I'm a member of.  I get pings for users that aren't me.  As an example, I get pings for @specific.user#3333 or @not.me#1232.  Why is that?  I don't need to be notified when they get a ping, as the conversation doesn't apply to me, and I don't need to interject any ideas to the conversation.  Is this a flaw in the matrix, or is it something that is purposely coded into discord?
