Are those forums still do -follow or not?

I really wonder if forum signature links still do-follow or not?

What I normally used were:

1. forums 。 ( I knew already it's no-follow)
2. ( I don't know but seems there was effectual when I did the links in my personal experience)
3. warriorforum ( don't know if do-follow or not, but still effectual )
4. .forum of tareeinternet. ( few people on that now)

Bove I am listing some SEO releavant forums and don't know if those sites nowadays...

Are those forums still do -follow or not?
