I should also point out that selling outside the marketplace is against our TOS for this reason (and many more).
We run a
stringent review process on the marketplace to ensure the seller can deliver what's advertised. If they can't continue to deliver at the same level or higher than they did when their service was reviewed, then we have the
Dispute Resolution section to keep the marketplace up to date. This goes a small way to keep scammers off the forum (we have many other methods). Try and follow the above and you should benefit from a reduction in scams. I appreciate it may be a little inconvenient to message on the forum sometimes but it's your call if that extra step is important to you or not. As my Gran used to say, "You can lead a horse to water, but you can't make it drink".
