Well... Trade volume can be faked by selling and buying own orders (if one wants to spend about 0.004 BTC per day), but if that's ethically correct is up to you. That happened at Cryptsy with the XPY too...
That is a good point.
I will put this statement out there just so it is clear. The Terracoin Foundation will not be engaging in any sort of unethical behavior whatsoever nor do we encourage supporters of TRC to do likewise even if it seems to help TRC. There will be obstacles in the future of TRC and we will never do anything unethical to bypass those obstacles.
