(My only demand is that they must at the same time purge 100% of my posts and comments from the database.)

You don't have that right.

I do, theoretically under the EU Right To Be Forgotton Law, but the US has no equivalent.

Otherwise, I shall continue

You want me to stop pointing out that 90% of what you post is garbage (technically bankrupt; completely irrelevant to the subject; never a single line of working code; unrecognisable and utterly borked pseudo-code; antiquated, thoroughly deprecated and superceded IT theory; all wrapped over in enough ideographic nonsense to make a typographer's eyes bleed), and meanwhile, you're just gonna carry on doing the same as you've been doing. I should coco.

A week ago, in a thread where some guy was having a trouble traversing directories; you post some irrelevant waffle about Windows having problems with iterating multiple directories concurrently because of resource issues.

Beside that it was irrelevant to the OPs Perl problem; the issue you describe wasn't in Windows 8; Window's Server 2013, nor Windows 7 or Window's Server 2005; nor Window's Vista or Window's Server 2003 nor Window's XP; Not Windows NT 4.0 or 3.51. The last time it was a problem was Windows 95/98, but then simply because of running out of memory.

The problem as you described it, manifested itself in DOS (& Windows 3.1 that was built on top of it). That's 20+ frikkin' years ago. Ancient history. The software Bronze Age.

If, as a result of your "flawed way to answer penitent’s questions"; that guy took your advice and went and completely re-wrote his entire application to avoid holding multiple concurrent directory cursors -- when all he needed was a couple of minor corrections to his code -- you've done him; his company; and maybe his career; real, and possibly lasting damage.

That should not -- cannot -- be allowed to continue unchallenged.

You want me to stop pointing out your crap? Stop posting it.

and, no, I have no intention of sending any dollars (nor, pounds sterling) to any lawyers (nor barristers).

Oh. Go on. I mean, if he's so desperate for work and so confident of success that he sought you out, may be he'll do it no-win, no-fee.

Heck. If what I'm doing is so heinous that it caught the attention of a barrister no less, then may be he'll do it pro-bono; to enhance his career.

Of course; it can only be defamation if it isn't provably true; and everything I've written, has been in direct response to what you've written; and that's all right here in Black & White!

(Of course, a barrister would have known that!)
