There are several ways to generate meaningless chat logs in group chats: 1. **Random topics**: Use a random topic generator to get some random topics from tools on the Internet, and then ask or discuss them in the group chat. These topics can be irrelevant, such as "What color socks do you like?" 2. **Automatic reply tools**: Use chatbots or automatic reply tools that can be set to randomly generate and send messages. Make sure these messages are generic and meaningless to avoid misunderstandings. 3. **Emoji communication**: Use emojis to communicate extensively, such as sending a continuous string of emojis. This increases the amount of messages without containing substantive content. 4. **Text chain game**: Start a text chain game where participants can send words related to the previous word but without substantive meaning. 5. **Quote lyrics or famous sayings**: Randomly quote song lyrics or famous sayings, but there is no obvious connection between them. 6. **Pretend to send by mistake**: Occasionally send some messages that seem to be sent by mistake, such as garbled characters or incomplete sentences. Please note: meaningless chat records may disturb other group members, so it is recommended to be moderate and evaluate the acceptance of the group. In addition, if the group chat has specific rules or purposes, the group rules should be respected to avoid causing unnecessary trouble.
