That isn't true. What they insist on is citation. That's why cheetah bot does not automatically flag the post. It simply detects copy paste. The sources are cited in cheetah's comment so there was no further action taken.
You can rearrange the words to avoid the cheetah bot, but if the citations weren't there it would still be plagiarism.
I can't be plagiarism if it's THE ACTUAL LINK to THE ACTUAL CONTENT. Unless someone SPECIFICALLY TAKES CREDIT by making an OVERT STATEMENT OF OWNERSHIP OR CREATION then they are making no claim of ownership, thus, no plagiarism.
Now, if they renamed someone else's content "as though they created it" and then "claimed to have produced it themselves", that's another story, but this doesn't seem to be what's going on here...
