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.
However, as I have not yet looked into that block explorer in detail, maybe GazetaBitcoin or SFR10 can rate it when they have some time.
Or someone else can rate it, because ratings are open for everyone.
