Omegle matches users randomly, and unfortunately, there is no guarantee that you will always be paired with appropriate or friendly users. To reduce the chances of encountering inappropriate or offensive users, you can:
1. Use Omegle's text-only or moderated video chats.
2. Disconnect from the chat and try again if you encounter someone you find offensive.
3. Report any inappropriate behavior to Omegle's support team.
Remember to always exercise caution and stay safe while using Omegle.
