I have buddypress plugin in my site. Everything was working fine but sudden since 3-4 days a bulk of spam registration happening in my website, more than 200 registration per day. The most of the emails id having ‘@spambog.ru’ in their email id. Please let me know what may be the reason for this.
We already have captcha in our registration, as well as wp-security, we setup the following in our site:
1. Its sending a hidden field in the form so if any human being fill the registration form then he/she can not see that field but if any spammer/robot filling it then it must fill that hidden field to detect spammers.
2. Blacklisted few IP addresses which sending spammers.
3. Added captcha in registration form.
4. preventing few bad bots
5. applied firwall
6. applied file system security
But still we are getting more than 100 spam records everyday.
