You acknowledge that fraud has been committed by @siamcat and his siblings. If fraud, then there is criminal offense.

If that's the case, you should make a report to the police in your country. Moreover, you and Siamcat live in the same country. Let the police act. Not that you make a provocation post like this on Steemit.

Moreover, I see your post impressed with the character assassination, in this case @siamcat.

For this, you may even be sued back by Siamcat for your actions.
