Andlimit messages to 500 characters. Mastodon is a microblogging system open source, meant as an alternative to Twitter. Anyone can create a service on the basis of the Mastodon, while its users will be able to see messages left by users on other versions of the project.
One of the most popular services on the basis of the Mastodon — Mastodon.social. Most of the users signed up on it after Twitter introduced a new system of response to reports. Now when you reply the name of the user whos meant tweet, not counted in the characters — this has led to the dissatisfaction of the users.
In the Mastodon the usernames are still taken into account when determining the length of the message. The restriction is 140, and 500 characters.
