Безопасен ли joinspotted.com?

The owners of the Spotted app have taken over hundreds of polish fanpages on facebook. They had the pages removed and their likes transfered to ***** All of this was done without fans' knowledge, thus I recognize such a behaviour as highly unethical. Below a message is shown that was received by an admin of one of the removed "Spotted: XXX" sites. "Hi Mikołaj, as a one time, non-negotiatable offer, we would like to initialise a mediation process with you and have our lawyers tell Facebook undo the merging of your page. All you have to do for that is to agree to a binding agreement with us to promote our app four times within two months (text/link/video or picture post, which will be decided and provided by us) after the agreement is reached. You will be considered as an official Spotted co-operation partner with the agreement. If you agree to this mediation, we will need your statement to do so, the name of your admin profile and the ID of your page and its name. Afterwards we will talk to facebook to unmerge your page."
