What does Twitter mean by exceeding the frequency limit?

Twitter exceeds the frequency limit, which means that the user's behavior exceeds the daily frequency limit of Twitter, resulting in the temporary inability to use services normally, such as refreshing pages or sending tweets. This situation may be due to a popular restriction adopted by Twitter on ordinary users who are not members, with the aim of urging them to buy membership services, the so-called "blue V-mark". This practice may affect the user experience and may cause some users to choose to leave. Twitter (Twitter) is an American social network and Weibo service company dedicated to public dialogue. Twitter allows users to update messages with no more than 140 characters (except Chinese, Japanese and Korean, the upper limit has been raised to 280 characters). These messages are also called "Tweet", and Twitter is described as "the short message service of the Internet".
