Having friends planets in scan could be a good idea, even if u have not manually scanned it yourself its there, if that friend is removed from your FB friends list, all the automatically added planets would disappear
(options that i could add to this (u cannot attack friends planets while automatically added, or you cannot attack their planets if just became friends (have to be friends with that person for more than a week to attack their planets) (for the ppl that do the trade thing in this fourm)
can u trust your friends?
(also good with this idea*
