how much does Y!A's closing down have to do with  Big Tech's censorship  that began in mass after Jan. 6 2021?

None whatsoever.

The real cause of this site being shut down is idiotic anonymous trolls. Like you.

in a way , yes.....New laws are coming out that will hold social media sites responsible ( libel) to clean up what is posted ( racism. slander, abuse ,porn etc...FAST or face fines = $$$$$$$$$$$

Oh buddy buddy buddy--it started before that. It's not new, it just escalated. The past 2 years of social media have been chock-full of purges and bans.

Yeah, good thing it's coming down.  I've been through literally TEN accounts and banned just for my political views, being on the Right.  I advocated people on here to use an ad blocker just waiting for this day.  Good stuff.  Go to Gab, BitChute and Telegram. hehehehe.... I declare victory

Apparently, YAHOO no longer wants to provide a soapbox for idiotic rants from trolls and other partisan hacks.

We can guess all night long. But it wont mean a thing
