WPROBot Unix Cron

Guys,

I set my wprobot unix cron to 1 hour . Problem is time interval of each of my posts is exactly only 1 hour apart.

I think G may find this fixed posting time interval suspicious and I am afraid they will be able to detect it. How to make posting time interval random?

Thx

In Options there is a feature to random time of post...set this..and set the time interval for posting to 1 day...doing this you will get random time posts everyday
