Eons ago I wrote using my TrueName. In those days the sun was brighter, the snow softer, Google was good, and unicorns danced on rainbows.
That was a long time ago, in the Second Age. (In the First Age, there was no spam.)
Now I write as John Gordon , and my TrueName net content is the essence of bland. Except for a forgotten TrueName Twitter account I'd used for a few months after the fall of Google Reader Social . That one is a bit spicy, and fully available to curious customers and employers.
Be nice to be able to clean that up and make it a part of my corporate persona. Once upon a time I think it was possible to do that, using things like Twitwipe, delteallmytweets, tweetdelete and so on. These days, however, those Twitter App sites are infested with spam and adware. Delete All MY Tweets seemed the least bad so I tried it.
It didn't work. I don't pay much attention to Twitter, but I do know as they turned to the Dark Side they did limit use of their API. I suspect none of these services work any more - I suspect they were sold and turned to the not-good-side. It may be possible to write an AppleScript or Python script to sequentially delete tweets using the twitter web app, but even there I suspect there are limits.
The best I could do was to Protect all of the Tweets on that account. That means anyone who wants to follow it has to be granted permission. Alas, because this is Twitter, current Followers are a problem. You can't simply return them to a non-follower state, you have to Block them. I didn't mind blocking the half that were spambots, but there were a few there who followed me from our Google Social days. Most don't seem to be active on Twitter any more, so I hope they aren't offended.
One last bit of the old net facade fades away...
 Yep, G+. I have a few G+ accounts, but my primary TrueName gmail account is G-.
