This evening I received about one hundred notifications of posts on the forum, all about a football game happening tonight.
After endless efforts to remove the bots and posts, I'm setting a higher restrictions on the forum, at least for tonight.
None site members will only be able to view the public categories (General Discussion and Basic Assembly and Setup).
Only site members will be able to view and post in the other categories (Software, Hardware, Clinic).
New site member registrations will need my manual approval. If you are accidentally removed from the site, please email to email@example.com to recover your site membership.
Sorry for the annoying notification emails if you subscribed to the forums!
I opened the auto member approval yesterday. It happened again just now. It seems that manual approval is always necessary.
