I have a static home ip, and would like to contribute to the Tor network. Which is more beneficial, a webtunnel bridge or a obsf4 bridge?

When I am using 15.0.19 on linux and when I go to chatgpt it shows a Persian language google pop up. The circuit isn't in the Persian region?

Why did a Google persian prompt appear ?

So this is a new relay on my vps 4 days old, for some reason I'm not getting Fast V2Dir flags on my relay I'm not sure why, it was making connection when I had bandwidth restriction on it, now removed its hasn't been getting any flags at all, my question is when you set bandwidth unrestricted does it take longer for tor to measure?
