They should not harrass you. Some do,and if so screen,and post for the elders to see.
An example that happened a few month's back. I was in my Junker transport. I had already made many trips,and hauled 12000 food,and 12000 scrap into Gamma for the sairs. I was scanned by many caps,GB's,and fighters. I always make sure they know i am helping. Then on 1 of my trips(ended up being last of day) some little sair did the ole "2mil or dai" I was like "you cannot be serious" I then stated on Open channel that i had brought in tons of food and scrap already that day. He then opened up on me,so i thrusted to trip,while firing back. Then along comes an Osie,a cruiser,and 2 fighters. They proceed to tell the lone fighter to halt all actions as i am "one of the good guys". He refused,and said i would not pay him. At which point the other sairs said "NP. We will pay you" and blew him to hell.
So you see they do support those who help in RP. But make sure you follow orders,and be nice. Also i always ask for permission to dock before i land anywhere. Makes them feel important,and all that.
