Yes, very true except a TYPE 1 FLAG isn't necessarily for a SCAM accusation.
So, you want to say that it is not necessary to create a separate topic linked to the type 1 flag, right? But if you link it to the posts of those accounts, it can be deleted at any time, and the flag appears to be disabled.
The solution is simple: don't create a Flag with the scammer's topic as Reference. Create your own topic in
Scam Accusations (or
Reputation in some cases), even though it doesn't need much discussion (
like this topic).
Based on LoyceV's suggestion here, but instead of creating a separate topic for each different user, each account. You can create a general thread about those accounts for yourself, and post all evidence of those accounts.
Each post will be a proof of an account, you can moderate them yourself. Too many topics will make them rampant, but a topic with lots of posts is great to manage
