Exchange — a catalog of channels whose owners are looking for partners to exchange reposts in order to promote and attract new subscribers.
Find channels with similar topics and send requests for mutual exchange of reposts.
If one of the channels is noticeably larger, you can offer your own conditions, for example: one channel will make one repost, and the second - two or three. In addition, you can choose whether to keep the post at the top for an hour, or not to make such a commitment.
The exchange is available in the Mini App and in the chat version of the bot, open and closed channels are supported. The display of closed channels can be disabled using a filter. To view the content of a closed channel, you need to join it (check the relevance of the specified links to join).
Interesting channels can be added to favorites, and uninteresting ones can be ignored. Channels must not violate Telegram rules, and published materials must not contain prohibited content. After two unfulfilled applications, the channel is automatically excluded from the search for partners. Unblocking is done by contacting Posterium bot support.
