@coco I am awaiting the theme to be updated for IPB 4.2 then upgrading forum. It's not a huge change but a significant change to the usual bug fix updates. I am hoping that the banned thing gets sorted on that version. I made the ban group cause this 4.1 version just banned as you mentioned. Upgrade will hopefully be this week, and will have a look at it. If it does the same thing, I'll try and get a work-around.
The Shed End Forum relies on revenue to pay for hosting and upgrades. While we try to keep adverts as unobtrusive as possible without pop ups, we need to run ad's to make sure we can stay online and continue to keep the forum up, as over the years costs have become very high.
Could you please allow adverts on this domain by switching it off. Some of the advert banners can actually be closed to avoid interferance of your experience on The Shed End.
