Could a person be at the same time legit enterpreneur and a piece of scammy shit?  Should we have attitude: once scammer - allways scammer? Or it is not that simple?

This is the problem with a person Matiss Paegle, (also Matīss Paegle) a person supposedly active in Latvia and Estonia.

He has been a central figure in proven bitcoin scams:

1) Asicvault: https://bitcointalk.org/index.php?topic=5186716.0 ; http://archive.is/4fDi1 ; he is a shareholder in scammy Aiscvault run by notorious scammer Hando Eilsen

2) Windhan: he is main person in scammy Windhan ICO: https://bitcointalk.org/index.php?topic=5114243.40 ; now its website dead etc typical scam indicators (more on Windhan in Kazakhstan and its relation with this "Windhan" here will be coming soon, waiting for information from Kazakhstan).

But the same person Matiss Paegle is a central figure in a seemingly solid enterprise called BaltCap Infrastructure: https://www.baltcap.com/team/matiss-paegle/    

And he promotes project  that also seems pretty legit: http://keepwarmeurope.eu/fileadmin/user_upload/Learning_Centre/Latvia/T2.5-1__Alternative_to_financing_of_infrastructure_projects_and_public-private_partnership_.pdf

 I am quite confused now as I plan to take legal action concerning Asicvault members in Latvia and Estonia.  Any opinion?
