Is it possible to programmatically bypass the anti-plagiarism system?

Question

Text analysis

There are sites that, for a certain amount of money, promise to increase the level of originality when checking for anti-plagiarism, without using rewriting. I would like to know if this is technically possible? If so, how?

Answer 1

Assumption: for example, instead of the word "diploma" in the resulting text there will be the word "molpid" preceded by a special "mirror" Unicode character (U+202E). Well, in general, replacing normal characters with rarely used analogues (unless, of course, they are not filtered in the Anti-Plagiarism system)

Answer 2

It is possible, why not? The resources offer automatic uniqueness promotion that passes validation. Each resource has its own algorithm, and no one will tell you how it works.
Here is an example of a resource https://antiplagiat.org. Use the service and study the result.
