I have similar questions as moonlight. i have invited 5 friends with my referrer link explaining to them what they have to do. 3 of them have agreed to help me get the companions.
Our deal was:
I grant them all the companions they need to level up
I give them all the food they need and if they run out then they message me to send more.
I give them anything else they need and help wheb theyre stuck.
They level up theyre companion level to 50.
Once friend 1 is done they send the conpanions and the wolves to friend 2 and friend 2 to friend 3.
Now when my 1st friend to complete the favour was done she asked me what she should do with other itemls like currency,trinkets,material etc.
I told her to send currency to friend 2 and the rest to me bc I didnt know what she should do with them.she stopped playing after she had her companion level at 50. Now my 2nd friend is also done and sent me the items,but I am not sure if thats fine.
The next part I am not sure how to explain.
I give them all they need to get to the goal.
Later I get everything back.
I also helped them in other games with similar"invite a friend" quests.
All my friends can keep whatever they want (currency,trinkets,material and also food)(when all 3 are done they also can divide up wolves and companions if they wabt thats up to them)
My profit:
Materials,misc,trinkets,wolves they dont want to keep,friend companions.
My Final question is after all that explaining:Is this fair that I get the things they collected after they dont play anymore?
As mentioned I dont force them to give me the things neither to play the game,They can keep wolves and companions they want as well as other items from theyre inventory. And I also helped them in other Games
