I have made many changes recently to stop new people posting links and banning many spam phrases which seemed to work initially. Now all spam coming through is from japan/asia and is all in a foreign language, a sample is below with no links:
라이브카지노✰█『 700ＢＯＸ.ＣＯＭ 』█✰라이브카지노,라이브카지노
I have added phrases to ban as below but they keep changing the characters everytime.
Our forum is a UK website and i'm running out of options to prevent this. I have had the questions and answer option set on registration, and have been changing the questions daily, but spammers are still registering all the time. I changed today to solve media captcha and within 2 minutes, new spammers where registering.
Has anyone got a similar problem with spam and any solution to prevent this? I do not want to approve new users manually , as we got about 100 genuine users a day and 100 spammers, so it would take ages for our moderators to go through this.
The ideas I had was to check users IP addresses and if they are not coming from an english speaking country then block access.
Also would there be a way to reject any posts that don't contain standard english/langauge characters?
