The service for promoting on Telegram is really useful if used correctly. It automates various spam actions to attract users, including chat invitations, direct messages and group mailings, story mentions, and neuro-commenting. All of this works similarly to mass liking and following on other social networks – users receive notifications, get interested, click through, and so on. However, in practice, this can annoy most people and lead to complaints. Therefore, there is a high risk of getting banned with this promotion method. It's best to use it cautiously and work with proxy accounts. The service itself works well. There is a free access period for the first 5 days, so you have the opportunity to test its functionality yourself (but it's better to do this on a fake account).
