Every agency page is the same scam.
If you read the message, it's always worded deliberately enough to avoid chargebacks. It's almost never "Open this to see XXX" but it's some bullshit like "Open this and then I'll know I can trust you with XXX" or "open this and then I'll give you access to my collection of XXX" or "open this, send an emoji and then I'll send you XXX" and then once you open it they keep stringing you along with more and more DMs to unlock until you give up. But don't worry, after that 10th message you're so close to being in their trusted circle, come on, just keep opening the increasingly pricey DMs.
