doesnt matter at all. You should judge his opinion and not who you think he is.
What if he maintains more than just 2 accounts? You wouldn't want to know if someone is astroturfing?
Facts and logic don't need names attached to them, they can stand on their own.
However, on these boards it is just his opinion. Anonymous opinions in digital mediums are largely worthless. Especially if one moment they are the "opinion" of the developer/creater/license.txt-replacer of Soiledcoin, but as soon as that becomes inconvenient they are disavowed. How are we to know if an announcement about Soiledcoin is legitimate and not a phishing attack if we cannot know the source?
Most important of all, if the creator of Soildedcoin cannot keep his own forum account straight, how are we to trust that he can keep a cryptocurrency functioning all by his lonesome.
