Update all.json (#243)

I am seeing a lot of domains which I am having trouble classify.
They are all named polkadot something (gold, advanced, bank) and always come up with a blank page only with an email address.

advancedpolkadot[.]com - "info@blockchain.st"
goldpolkadot[.]com - "info@blockchain.st"
polkado[.]com -  "info@blockchain.st"
polkadotbank[.]com - "info@blockchain.st"

I would like to check with the team if this email rings any bells. 

If not I suggest to blacklist those just in case, despite them not serving bad content right now.

My suspicion is that those could be used for
- cybersquatting (re-sell domains for higher price)
- SEO reputation gains (and future advertisement placement on yahoo, duckduckgo or google leading to the fake polkadot clones showing on top)
- GeoFenced phish - serving contents only to users of a particular country.
