friend request messages & spam recommendation

It's been five years, and we don't miss skype anymore. However, i think you guys should take note of how useful it was when adding a friend and you could say a message like "Hello, this is so and so. I need to add you because of blank."  These days a lot of my friend requests to old friends are going ignored because their big company owners now and probably get spammed 24/7 but please add this as a feature.

Also, fix the mass mass dm advertising, this can be reduced by adding a captcha option for server owners.
