It is verified too. That means this account has not changed ownership. But what about merit abuse??? Would you like to say anything about merit abuse?
I will quote @theymos here:
Merit sales, transfers to aliases, back-and-forth trading, etc. are not much of an issue. All illegitimate merit will decay, and will account for a tiny and very expensive fraction of the total merit economy. It's basically a rounding error; fight it where convenient, but waste no sleep over it.
So I think unless with these a Merit source it is difficult for them to continue to get more free merits and therefore no one will hire them, which means that they are forced to create high-quality posts.
Therefore, it is better to put a neutral trust to remind the possibility that these accounts are alts and to take this topic as a reference if any additional evidence is found, and then a negative trust can be given.
