I ran a bunch of domains through scrapebox alive check. I got a bunch of dead ones. but when I tried to go to the dead ones using my browser, some of them were actually alive. I would like to have a more accurate way of checking dead vs. alive. in the options tab for the alive check add-on I have these: 200 300 301 302 201 202 303 307 203 204 do I need to add more to this?
