If you are very bad in math, I’m so sorry but don’t worry, there is always a calculator available in your computer *LOL* From now on, you must do your math in my blog.
When I started using WordPress, I don’t have spams, then I got some spams once in a blue moon. Usually, one only. Lately it’s been like 4-5 in one go. Almost every 2 days I will get spams. Still not very serious but I can’t stand it anymore! Unlike some people can get at least 1000 of spams everyday but wait till so long than get a plugin for it.
So yea… You have to do your math now.
