Not that I've seen on my end for tickets... Only time tickets I've known about ever being marked as spam is if its done repeatedly over the same issue and tone taken with the GMs.
If its on Shaiya's end, Consider.ez, I'd suggest to compile the ones you're having issues with and ask one of the Shaiya GSes or a forum mod to ask a GM to look into it for you. That for worse case, send a ticket to Billing Attention: Superman0X in the subject line, and explain to him exactly what is going on, or possibly PM GMPaladin to have a look?
I'd offer to do it myself for you, but if its Shaiya related, I can only forward tickets for Scarlet Blade related issues. I'm sorry.
