The real problem is that accounts like mine seem to be borked. You can flag those posts as much as you want to. I don't get notifications about it. Seems to be different for other mods though...
So... is there any way the kind folks at Opera ASA can look into matters to rectify that, sooner rather than later? Perhaps even going so far as to create a new account for you, if needed? Right now, the spam has been piling up in the Opera Windows forum, and I don't think the spammers have any plans to lighten up in the foreseeable future...
Or perhaps we need to re-start the Spam Report thread: https://forums.opera.com/topic/976/report-spam-posts
