Depending on the instance you're on this likely *Does* require purposeful intent though..
I.E. people are being tricked into "doing the wrong thing" by the auto complete popups (for hashtags) that are supplied from their instance's server(s)
"The system" defaults to showing you "auto complete" hashtags and the auto complete versions are almost always in lower case. So, if someone selects the system supplied suggestion.. they get "the bad result"
