His communication skills are considerably weak so most of the times, he finds difficulty in understanding. I'll personally warn him as well as ELK will who knows Spanish to make him aware of it.
Besides that, We've just recently announced this rule and CTF community isn't fully aware of it. It will take time for them since most of them hardly visit forum. I've posted this rule at our discord channel too but for a week or sometime we or at least I am going to be lenient with this. I'll give them some time to be familiar with it.
I'll lock this report, thank you for the effort, Aegon. In the future, if you can record for some more minutes would be nice.
