Fun experiment: if you see a greentext on reddit, try typing out one of the sentences word for word, and pasting it into the reddit search bar. It will show you one post, and that will be the post you copied that sentence from.

If reddit has the ability to mass OCR and index every image for searching, then almost every other platform has as well. So things like screenshotting text and posting it will still get indexed and linked to your account. Insta algos will probably derank your account if you have words like Palestine, Gaza, etc. even if you try to bypass that by screenshotting them instead of typing them.

Another aspect of this is sending images by WhatsApp, only doubly so, because those images end up in the gallery, and most phones nowadays automatically OCR them as well. This increases your attack vector, depending on your threat model, I guess.

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
