its not a trick or a trap. they simply cannot come out and say, "1 million is the cap", because then those wanting to abuse it would transfer cash for the amount of $999,999. It may be vague or annoying to some, but it has a purpose. I'm sure just as with the pushing ban appeals process, if you were banned for using cash transfer, the moderator would go and look at the reason listed for the transfer, if the cash was actually used for the stated purpose, was this a one time thing or happens frequently, are the accounts from the same IP address, etc, etc, etc... Meaning, as stated, they would use their best judgement to determine if the player in question was in fact pushing. If you find yourself sending an amount of money that you think is questionable, then do not send it. There are workarounds available. Ex: If the cash is for the other player to buy gear, then buy the gear for them and relist at cost, then nothing to worry about, as long as that was the actual intended purpose.
