It does make it harder depending on the platform and what you're trying to accomplish but yes, OCR has been near perfect for well over a decade now, it's basically a commodity software at this point. Unless you're encoding your image like a captcha or using some riddle or something as extremely basic encryption, image posts with text and text posts are basically the same thing.
There are still use cases for text as images but "getting around platform filters" is rarely one of them unless you're coupling it with other methods as well
