Or there any easy "share a link to friend's wall" scripts?

I have a link on my fanpage which I would like to share to ALL of my friends.

The only problem is that Facebook will only allow you to share to one person at a time.

Are there any bots or scripts which can do this on auto?

You can post the link as a status update for that fan page, and it will be posted in all of your fans news feeds. If you want to post it individually on each of you friends walls your going to need a program like FFAP. I don't believe there is any other software out there right now that is capable of doing the tasks that you need. FFAP is 599 but you can pay in monthly installments of 49.99. I use the program myself and have a pretty good return rate on not getting banned.

ffap is still good you can use that i really don't know if there any other software out there which still works even though ffap has bugs but it is still the best out there

FFAP allows you to share your fan page to your profile wall which will be listed in your friends' Newsfeed as well.
In that case, most of your friends will see your fan page and would probably like your fan page. Thanks.

Lol im currently using a software that cost 100bucks and can do same as FFAP except my software has events creator and its 500bucks cheaper.
