I) All auction, buying, and sales threads should state which forms of payment are
being accepted/offered, for example "TC only" or "high-value items".
Also note that posts inquiring about the preferred payment option which aren't offers are treated as useless, and punished accordingly. If form of
payment wasn't stated clearly, it should be assumed that both items and TC are accepted.
C) Do not attempt to sell, or pay with items or Toricredits that are not in the
inventory of the account that is posting. No; "It's in a bank account". This also covers the sale of items currently in the market.
