I am having major issues with my site, I have made a quick video which shows them if you could take a look and figure out a solution I would be forever grateful.
Unfortunately, most spam these days does originate from real people so automatic processes to keep them out are not easy. Jamroom does have various options amd tools to help site admins control the situation that include user probation, IP banning, offsite URL detection and adding signup questions but they do involve manual intervention by the site admin to approve or delete new accounts etc. Its part and parcel of running a website these days I'm afraid. We regularly do it here at Jamroom on this site.
You have also sent this as a support ticket so will follow up further with you there.
Thanks
