I'm not native english speaker nor a professional in any way at computer science so I don't understand all the details and terms you're trying to explain and use. This is something I'll try to fix with further education and I can always come back to this answer to fully understand it at some point in time.
I did however understand(or did I?) that it's not wise to store every post as plain text data and it rather should be coded into a string that could be searched,processed and stored efficiently.
Thank you for the detailed answer!
Interesting. So majority of people isn't informed enough to see this problem at all and those who know aren't voicing it.
