Add etherText?

[epheph]

Given that etherText has been banned by twitter, and bot operators frequently use EtherText to communicate, this might be a neat place to add EtherText messages found in calldata on Ethereum.

The detection is very simple.

1. look for top-level call data,
2. decode it hex->ascii
3. determine if it is word-y. i just look for spaces > 2 and ratio of spaces:len between 2 and 10 (surely there's a better/smarter way)
4. and then there's a blacklist of prefix's from wallets and exchanges like "tx from HappyWallet" or "Exchange order #9551", you'll want to filter thouse
5. Probably want a stopword list (you'd be surprised how much nasty racist stuff shows up in ethereum call data)
