The goal of the AI act is not to determine if an "oh yeah!" comment was AI generated. The target is long papers that falsely claim human review and can have real significant consequences.
E.g. research paper, law makers, lawyers, state policies, notaries,...
These are much longer content and thus statistically they will disclose a better guess at AI generated content.
Asking another AI to paraphrase will not erase the mark (which they are unaware about) but rather cumulatively add their own mark and make it easier to detect.
The problem is not to use AI, but to endorse the responsibility of the content you (as a human) deliver and somehow make sure that fake-news, biased content or unverified output is detected as early as possible.
