You asked in the tags what the deal with "thankyou" was. I'm going to assume you actually want an answer, so here you go.
When the Spamton Sweepstakes 2 dropped (ie the silence ending update), getting to the end of the 'ARG' path (/ramb -> /romb -> click on the invisible square -> /chapter3 -> infer the existence of /chapter4 -> click on the red dot to get to /chapter4/message -> solve the invisible keyboard puzzle to get the letters to spell thankyou, replace "message" with "thankyou" -> /chapter4/thankyou) would bring you to a certain screen.
It had two input fields, and a button. The title of the page was "How long did it take her to smile?" and with a bit of guesswork, it was determined that the first field was an input for an email address, and the second field was an input for... anything you wanted.
If you didn't input anything into the second field, text would appear saying "She never smiled?", suggesting that the second field is where you put the answer to the question the title of the page is posing- How long did it take her to smile?
After around 12 hours, the input fields shut down, and you can no longer submit responses. A bit after this, those who inputted an email address that was also signed up to the UTDR Newsletter got an email with no subject line and no text. Unless, of course, you thought to input a unit of time into the second field, in which case the email was a simple "You answered [TIME]."
It seems that it assumed seconds if you didn't specify a unit, but if you did specify a unit, it would keep track of that, ex "12 days".
To our knowledge, nobody has actually gotten a unique reply from this. It doesn't seem to have a correct answer..? Unclear what the purpose of this was.
In the weird route of chapter 4 the red dot and "Thank you" was said, but it's still not entirely clear what this meant.
See Mollystars' video on Sweepstakes 2 for more information, they went over the same things I did.
I hope this helped!
