To my understanding, as long as they're not using a VPN, yes. Now as another commenter pointed, if it's a website that the GFW blocks already anyway (e.g. Reddit), there's no point. So first thing to do would be to check if the GFW blocks your website.

Checking whether the GFW blocks the website in question demonstrates that it remains accessible despite the keyword injection: https://blocky.greatfire.org/detail/684702/https%3A%2F%2Fwww...

That only shows today, and the keyword has already been removed for a while.
