Nope, Bitcointalk.to doesn't work for few years already. But it might be other phishing websites - I guess there is plenty of such websites.
It would be interesting to know in what way OP tried to access Bitcointalk. If tried to do it through Google search results, it's very likely that it was phishing website.
Well there was this thread back in 2019 that listed some of the phishing sites-

I thought that the "to" ones are like sort of mirror sites back then, but thankfully I never bothered logging into that one.
I can also confirm that most results are showing the "to" ones like what mk4 said, when I was trying to search for threads through Google search in my mobile phone.
I just saw that the domain was up for sale already.
