My story: My suffering
When I get started with my wordpresss Mu powered community portal I nearly got 30-50 spam blog (sblogs) signup every day. It made me seriously think over fighting with the spam because these spammers . But what made me surprise is , I have tried every possible spam prevention tools like captcha and Recaptcha with my blog but everything seems to be sucks .
The sbloggers are
- Stolen my web spaces by creating numerous blogs
- Registering various domains under their name and making not available to the real users
- Directly attacking the quality of portal ( if real customers found bogus or spam users information with our blog they will surely debut with genuine of the information present in the blog)
