I have no spam filter.? MY isp has none.? I know this because I called them and requested to have access.? There is no spam filter. ??I can't empty what I don't have.
Also I did not mark as spam anything in io.? I was incredibly careful as to what I clicked on in there so I would not hurt my group.
Looks like you marked a Groups.io post as spam or a post got diverted to spam by your ISP and then you emptied your spam folder. When this happens, you automatically get unsubbed and receive the message. Be sure to re-subscribe within the 3 days.
