I have Sender from Lizard, in addition to Inviter, and I plan to purchase Parser. I like this software because Sender has inviting features and excellent parsing settings that are lacking in Inviter. However, when it comes to promotion without sending messages, Inviter is simply essential. Ideally, it's best to use all the company's modules, so you won't have to rely on third-party programs and cloud services. Inviter helps promote through inviting and mass liking. You can invite people to groups as well as join them yourself using different accounts. When joining, it's convenient to use pre-parsed lists, especially if you have a good parser. To avoid blocks, proxies are supported, and it's advisable to set intervals between actions. But unfortunately, there are no guarantees against blocks. I've already lost two accounts, but I wasn't too concerned about security. I haven't found any significant drawbacks, except that there is no demo version, which means that those who want to test the service will have to purchase at least a monthly package. A parsing service is also necessary, as it is not included in the current functionality, and it is truly needed (the developers have planned a separate parsing module, but you can also use third-party solutions).
