If it's done ”” or suspected to be done ”” with criminal intent, yes, it would be reported (SAR/STR)). But if it doesn't come across as criminal, it's likely just treated as a T&C violation and the accounts are closed (they might let you keep one).
In the example of Bybit, it's very clearly a T&C violation:
Registration of multiple trading Accounts would be a violation of these Terms and may lead to immediate termination of these Terms and the Accounts involved.
Chances of getting flagged are hard to quantify since a lot depends on the user and what data you provide.
If you log in from the same computer (even with different browsers, VPNs, wifis), they can easily connect the dots automatically using any half-decent fraud prevention or risk management tool.
It'd also be quite easy to cross-reference and find a match on ID number (some countries put national ID number on all ID docs), or date of birth + name + country, and other variations like that. Checks like that are often performed automatically with narrow search criteria, and wider searches are done manually from time to time.
