I think that those coins associated to hacks shouldn't be accepted by any service. They should be immediately confiscated and donated to open source projects or other causes, like eXch did.
Some services tried to blacklist coins or addresses associated with the hackers some years back, and we went down that familiar path of censorship and how bad it is to the freedom to privacy in crypto. 
Basically, not every one will be happy, even those who don't support the hacking but are pro censorship resistance in crypto or at least Bitcoin.
