--- Comment #10 from Rosanne DiMesio dimesio@earthlink.net --- Maintainers already have the ability to delete spam; that's a key part of their responsibilities. Unfortunately, not all maintainers are doing their jobs.
If you see spam, first report it to the maintainer, and if he/she doesn't respond in a reasonable amount of time, report it on https://forum.winehq.org/viewforum.php?f=11.
