I have no idea what to think right now..

"So I was trying to invite people to my FC when I got the following conversation":

FC leader> "I was wondering if you 2 would like to exp faster, see if you 2 join my fc, you get a 15% exp bonus for being in it. Also comes with a large house to hang out in"
The person being recruited> Isn't that cheating?
FC leader> how is it cheating? that is how the game was made
The person being recruited> that seems like an unfair advantage to me
FC leader> why do you say that? a lot of people are in fcs using it, and ofc nice house to hang out at hehe
FC leader> it is a pretty standard thing
The person being recruited> no thank you, i do not want to get banned for cheating
FC leader > ???????? *shows link to loadstone explaining FCs*
FC leader > its not cheating

*ends there, no reply back*

How can anyone think a FC buff is cheating? or joining a FC?
