No, because it takes time to review tickets. The auto-squelch is a near immediate response to Gold Seller spam. The effectiveness of their advertising relies on how long they’re able to spam their message for. The longer they can spam for, the more people it reaches.
Here’s a compromise I feel is a good middle ground that Blizzard may actually be willing to entertain:
Get squelched by trolls, GM sees you’re not selling gold or characters; GM bans trolls. Sound good?
