Make it 100%.
This is a scam and I usually see them not from here but mostly in social networks. So, they're coming here to come and get those members that might actually believe on them. Don't get outside and let them do the talking of what they propose, or simply avoid and ignore them so that there won't be any further discussions about it. It's not worth it of your time to talk to people that are wanting you to contact them through their personal number or, is that really a personal number of theirs and not just a bought account because it's used for scamming?
