Forums:
I once again offer to help with the forum spam.
If I had the password I would try:
- stopping everyone from making more than 2 posts a day
- stopping new users from posting for the first day
- let other people delete posts automatically (help the moderators)
- make more moderators. More people who can quickly approve requests to delete threads and ban new users and new sign ups from the abused IP
- backup, make that backup public and let a group of 3 people I trust help run the forum together
- install a captcha
Even just one of these things can help the situation.
Please if you block China, just block the mainland and not Taiwan, Hong Kong and Macao as these aren't really China and for the most part, don't really want to be China either.
