"Can you move this conversation to Telegram?"
Scammers often move conversations off-platform to avoid detection and reporting.
"We just need a small processing fee…"
Legitimate opportunities don't ask for upfront payments.
"Your account will be restricted in 24 hours"
Urgent deadlines are a common pressure tactic used in scams.
"I have a job opportunity that pays $5,000/week"
Offers that sound too good to be true usually are.
