Report Users without clicking on their username
There is a clear and present epidemic of bot accounts on Twitch (eg: The innumerable 'hoss_###' accounts) harassing streamers and viewers on Twitch, especially smaller content creators.
These bots are using a malicious third-party extension which can capture and log users' IP addresses whenever said user clicks on their name in chat, to view information about them as a user or views their channel.
Since the report feature currently requires clicking on a user's name, this exploit undermines users' ability to moderate and combat these bot accounts. There are ways of banning these users directly from chat, such as Nightbot, but this does not solve the problem as the users themselves still exist and cannot be reported without potentially falling victim to their exploit.
Implementing a separate web form to report users by their username, here in the Twitch Support pages, would assist greatly in ensuring these malicious actors are identified and properly taken care of.
