Can I get another extension in Thailand after multiple extensions and border runs?

The user has been in Thailand for 240 days on a visa exemption, having used 2 extensions and completed 2 border runs. Although some comments suggest that another extension could be attempted, there are concerns about the risk of being denied re-entry due to the length of stay and the immigration officer's discretion. It may be advisable to leave Thailand and apply for a long-term visa instead.
