You're fine to use an exchange account to receive funds from friends, I don't think the exchanges are against that.
I have some cash lying around and I don't want to put the cash into my bank account (the bank might ask a lot of questions).
So I thought I would buy some btc from a friend of mine, pay him in cash and ask him to send the btc from his wallet to mine.
I think it has indeed to do with funding in fiat money from a bank account.
I just wanted to make sure before I ask someone to transfer btc to my wallet.
Thanks for all of the replies.
