Okay, so just to be clear you decided to fight spam, by spamming the support desk? Look, I get it. It's annoying as all heck to be inundated by tells from random RMT asking you to 'plz buys gils', but reporting each and every one is counter-intuitive. A number of these will be linked to the same accounts, or will at least give SE a base on which to investigate further RMT you have received because they can read your tells.

So, report once and let their investigations team do their job of investigating. Spamming is not doing anyone any favours, least of all you.
