Initially, I thought this might put some pressure on Bitcoin_Arena to respond, but I guess it's better to ask than to wait for a few more months [I'll do it shortly].
Alright, if you want to send a PM, you have my support, of course. I'm sure you have GazetaBitcoin's support as well and it's also okay if it's taking some more days / weeks as we have waited already quite some time now to get an official rating.
And once we have an official rating, GazetaBitcoin will update the table.
The good thing is that you have rated other explorers in the list too, so it will be easy for you to determine the ratings based on how you see other explorers vs 3xpl.
