I quite often will gift people things, such as points or PMs, I dont mind helping out but there are some rules for who I gift to from now:
Gifts are for good friends and people who have done something epic for me, which usually means I class them as a close friend!
Some points for good friends, and more or Pms for close friends.
A good friend will want to chat and talk about stuff on comments ect, maybe draw the odd basic picture ect.
To become a close friend you have to want to be a friend, and that means chatting regularly, via skype or notes, interacting and generally being there for each other, or making a really epic gift.
I may occationaly deviate from these rules myself in a special situation
