Marking it as "#ad" in the hashtags or description or whatever is exactly what the advertising regulator says is required in the UK.

It's the bare minimum, but its compliant.

And the UK has (oddly) some of the stronger legislation/regulation around marking advertisements.

YMMV when it comes to advertising finserv tho, the other regulators might fuck you even if the ad disclosure is done correctly.

Is that odd? The regulator (the Advertising Standards Authority) is and has 'always' been pretty hot on misleading/etc. advertising in print, radio, television (pre and post digital) media. If anything I think they came quite late to non-traditional online advertising.
