I’ve not signed up for it either.
Part of the reason is that when i talk shite on the internet i like to do so behind a username rather than my real name, prefer the degree of anonymity it allows. Back when i first started using the net (around about 1997) i contributed to a few websites using my real name…alot of what i said is still around and the top google results if i search my name are book reviews.
The first return is Mein Kampf, the review was originally about how crap the writing was, that nazis are bawbags and how they should follow their leader and shoot themselves. But the text of the review is gone, what that remains is a link “Mein Kampf reviewed by….” so it probably makes me look like a nazi 😐
