Bitcoin blockchain image indexer and uploader. Uses fake P2PKH address.
At some point it stopped using Bitcoin mainline and moved to Bitcoin Cash instead: www.newsbtc.com/news/bitcoin/cryptograffiti-rejects-bitcoin-core-bch-now-available-payment-method/ and therefore became useless. Existing indexes seem to have been broken as well.
Also, based on the timing of Figure "Erich Erstu", this service may be responsible for a large part of the raw JPEG images present in the blockchain from block 416527 (2016) onwards. This is also suggested by the comments at Figure "Tank Man".
A Quantitative Analysis of the Impact of Arbitrary Blockchain Content on Bitcoin gives the interesting insight that all its transactions seem to return change/fees to one or two given addresses, thus making it very easy to list all their uploads if they were consistent! So all we need are some starting points, which we have mostly due to ASCII mentions of the site on known inscriptions, all of which have a few common spent addresses at the very end:
so we just have to solve get all Bitcoin transactions from and to a given address and we are done. Blockchair shows about 800 entries as of February 2024, between 4f94f97eb156b8563a213bb292314a0bd9c95b39afc521fc5965d050daab2a78 (2014-03-02) and ac5f4ea03597b43a72fb8ab42bd5384629f87f4f4abc534f38b8c15148ccaf9f (2017-10-12): blockchair.com/bitcoin/outputs?s=time(desc)&q=recipient(1MVpQJA7FtcDrwKC6zATkZvZcxqma4JixS)

etchablock.com was presumably an inscription service that allowed people to pay to have Base58 messages inscribed on the Bitcoin blockchain.
The service failed to gain popularity and not much is known about it. justdropped.com marks the domain as having expired on 2013-02-03.[ref].
The first known mentions of the service date back to December 2011, when it started self-advertizing in the blockchain around tx 8ffacbb18f63576fe323cbf2acc6c4c01c86aadf13d8352cfdd39d91916d98c8, block 156164 (2011-12-05) by repeating the following 3 messages 80 times:

The website was down as of 2021, and there are were decent archives unfortunately: web.archive.org/web/20130301000000*/http://etchablock.com/.
Some surviging online mentions include:
  • www.reddit.com/r/Bitcoin/comments/s9cra/comment/c4d5x9b/ Gold, Silver, and Bitcoin spot prices are now only a call (or text) away (2012-04-14) suggests that the creator is a "Jonathan Ryan Owens" since user jonathanryanowens comments:
    Aside from Bitcoinduit, which was the first project we worked on for the purpose of investigating the inner workings of the bitcoin network and double spend threats? Ok.. here's a few: We developed custom bitcoin signing agents (etchablock.com), we did the first facebook bitcoin wallet (yougotcoin.com), we have our own custom c++ libraries that completely reimplement bitcoind for our own applications, we have an actual working double spend detection and alerter infrastructure, and also a coming slew of apps related to microlending and fixed exchange services..

This website used to allow embedding text messages with OP_RETURN, here's an archive from 2015: web.archive.org/web/20150718052659/http://eternitywall.it/
As of January 2024, it seems to read-only mode, where it simply indexes matching transactions that were made via other means: web.archive.org/web/20230929075331/https://eternitywall.it/
There were 3191 hits for the search term:
git grep '\bEW '
in our data starting with tx a3b3af21514bd79a4cbcac9916a8514636a72d813539192214542fd85247082e (2015-06-24):

EW May our friendship endure, signed by hg, kty, wjj, and xyz.
no doubt initials of 4 Chinesepeople. A blood brother oath comes to mind, akin to the Oath of the Peach Garden. Will these four be the ones to take down the evil dictator Xi Jinping?
The very first message gives away the name of what we assume is a web-based upload system, "EW" being its advertisement signature added to every message.
Running bitcoin-cli:
