The optimal dimension of the avatar on Telegram is 512px by 512px, and it’s recommended to use PNG format to deliver an unpixelated avatar. Your posting frequency depends on the topic of your channel. If you have a news channel, it’s OK to publish new content every day (or even every hour). For other industries, stick with 2-3 large posts a week. Earlier, crypto enthusiasts had created a self-described “meme app” dubbed “gm” app wherein users would greet each other with “gm” or “good morning” messages. However, in September 2021, the gm app was down after a hacker reportedly gained access to the user data. But a Telegram statement also said: "Any requests related to political censorship or limiting human rights such as the rights to free speech or assembly are not and will not be considered." Telegram has announced a number of measures aiming to tackle the spread of disinformation through its platform in Brazil. These features are part of an agreement between the platform and the country's authorities ahead of the elections in October.
