well,
we use to have old designer who use to work with programmer(so though he doesnt know programming,he had rough idea where to change and all to set up those scripts,system he worked with us)

now he have left...

but took some of our system and script customization coding with him and now he has started his own site....which is 80% similar to one of our portal.....some sections have only color difference....same structure...same coding.....

now it is appearing along with in google SERP as well....

so what can be done...?

(well,legally there are less we can do as it is difficult to show the customization was done by us.......and we donot hold copy right of the scripts we have made...)

we requested/threated him to put the system down which were very similar(as it is same code).....but he has not done that.......

so what can we do now?

He runs adsense....i have heard adsense disallow sites with exact layout ...can we do some thing here....

what can be best idea....well to be frank it has been strange situation ...now i cannot go to my own codes and start searching where security holes are.......
