Moderation on this service feels like playing Russian roulette in a casino — you either get lucky or you don't. Most of the time, you don't. When I asked why a text message I successfully sent a month ago was blocked, the response referenced advertising laws but lacked specifics. There are no clear criteria for why messages get blocked. I have to struggle to extract information from the managers, as they respond with one-word answers and to completely different questions. Overall, my impressions of this company are very negative.
