You have been here on Hive for quite some time now so its expected that when you invite people here you guide them properly and informed them of the rules. Sure, we don't have control whether they will listen to us and still break the rules (based on experience) but as the one who invited them, we should be responsible enough to always informed them of the rules so they can thrive here on Hive.
You are also well aware that we have a Filipino community Hive PH where we have monthly webinars about Hive, you can always bring your friends over there to attend and be informed about this platform.
I'm sorry for this. I did not expect it to happen. I'll make sure that it wont happen again.
