Related to T304375: Remove runtime handling for "legacy" rows and codepaths and specifically https://gerrit.wikimedia.org/r/c/mediawiki/extensions/OATHAuth/+/773918...
It seems StrikerBot (and StrikerTestBot) are doing deprecated queries like action=oathvalidate&totp=foo
These queries should be updated from doing action=oathvalidate&totp=foo to action=oathvalidate&data={"token":"foo"}
Seems this may come from 2 different User-Agents: Striker mwclient/0.10.1 (https://github.com/mwclient/mwclient) and Keystone mwclient/0.10.1 (https://github.com/mwclient/mwclient)
