Short answer no.

This is the first time when a PoS coin is in risk of a 51% attack from thief.

This is an very important lesson for crypto and specifically to PoS coins.

It could happen to any PoS coins. Instead of attacking vericoin, i think it is more important to focus on the real problem.

I expect exchanges and it's users to be more vigilance after this incident.

We learn from the problem. We evolve. This is why we have decentralised exchange like BitHalo from the blackcoin developers will reduce the risk of a large scale thief.

Educate people, not attacking people. This isn't a very friendly environment an investor would like to put their money in.

Stop digging your/our own grave.

It is your own stupidity if you allow that to happen again.
