They say the internet never forgets, making 'offense archaeology' possible.
Digging deeply, Guido Fawkes is really going to town on the newly appointed editor of BBC Radio Wales and Sport, Carolyn Hitt.
She's clearly one of life's perpetual Twitterers.
In recent years, she's keenly declared her dislike of Brexit and Tories, and declared that, though a life-long Labour voter, she'd voted Plaid Cymru as that was the party that 'reflects unambiguously about how I feel about Brexit'.
She's also - within the last five or so years - written articles slamming the Welsh for voting for Brexit, backed Welsh independence, expressed admiration for Jeremy Corbyn and slammed The Sun, The Daily Mail and the Daily Express as “far-right rags”.
So her views are clear.
I've just done five minutes of digging myself on Twitter using the terms 'UKIP' and 'Farage' - which are so fruitful because they tap into how certain people reacted to the rise of UKIP, Nigel Farage and Brexit and, ultimately, the 2019 collapse of the Red Wall. So here are some further tweets from Ms Hitt:
- I will never ever understand the appeal of Ukip in Wales.
- UKIP 2nd in RCT. 1901 Rhondda census listed greatest number of people born elsewhere living there in all UK. Immigration built communities.
- Nothing depresses me more than Welsh support for UKIP.
- Just when I thought I couldn't feel more disillusioned UKIP trumps Plaid.
- I find the level of coverage they get absolutely ridiculous. Farage on #bbcqt 15 times without a single MP.
- Oh bloody hell Nigel Farage on telly AGAIN. Time for bed #bbctw
She's landed quite a bold claim there in saying that she'll 'never understand' the appeal of wide swathes of Welsh opinion. Hopefully, that's not true, given that she's now in charge of the BBC's Welsh radio output and is Charter-bound to understand all shades of public opinion, whatever she thinks of them, and then to treat them fairly.
And the last two there are particularly interesting in the context of BBC impartiality. The partisan Ms Hitt was slapping the BBC for inviting on Nigel Farage.
The question, of course, is whether she'll be able to hang her leftist, anti-Brexit, pro-Welsh independence coat up at the door now she's been appointed to a senior editorship at the BBC.
