Just wondering who is creating these transactions:

https://blockchain.info/tx/db195e4bfcfb3cc6d47f8d6231cb59e543c31e01d196d557457bca0fa5c1aba0  ... 20402 bytes

and so on.

These transactions store some text data in blockchain with P2SH technique.
It is not too difficult to create a tool to get data as a plain text from these transactions (but I do not have interest to do it)
You can download them as binary and view in hex editor. You will see something like:
