I would think, being a resident here, no one would ever consider you to be trolling or spamming. I think following up with a text or email to leave a review is a great idea to do. Sucks you have to pay for it but if it is helping and worth the cost, that is awesome. I would think you could have techs text a link after they do a service and get reviews that way for free and I bet techs would be happy to do it if they earn a spiff when reviews are left. Just a thought.
