You missed it. OXT is in OP for months as the last update time is 27 October 2020.
Yes, you are right. I looked for it before posting it, but I didn't see it. And now, after seeing your post I looked again and again I did not see it, until I read the post for a second time. Most likely because it's not in the main list from the OP... My bad. Thanks for pointing this out, hd49728!
)Later Edit: I would like to propose now https://bitcoinwhoswho.com. This one isn't mentioned in OP and it has very interesting features: you can see the last IPs of the transactions, verify if the address was tagged in scam activities, you can see if it was mentioned on websites (and on which websites), you can check "bitcoin ownership and wallet balance by name, bitcoin address, email address, url or keyword" (I didn't verify all these yet) and you can also see if repeated inputs came from an address or repeated outputs were sent to an address.
Added, at first, where it didn't seem very user friendly, I was a bit disappointed but it seems to be an interesting explorer. | Name (link) | Bech32 supported? | SegWit-Addresses (P2SH) identifyable?* | Usefulness (subjective rating  ) | Rated by | Comments |

(I've just taken a random address posted on the site flagged as "scammer address"):
https://bitcoinwhoswho.com/address/14s4i1WRPQ4BdwGtt38oumwdebKdvVdUfG
Scam alerts are added (I don't know how such reports are determined)
Website appearances and
Transaction history (where connected websites are listed; someone got scammed and reported it on Bitcointalk here) ^^
But we can't view transactions, only Bitcoin addresses can be viewed.
