Oneye pointed this out to me earlier, Alpha is not a very unique name and others use it in multiplayer.
I rarely play MP, but from now on if I play MP I'm going to put [BA] behind my name (Abbreviation for Building Academy).
Also, if that person uses built-in ships, poorly designed ships or allows max money, you can be sure that it isn't me.
Most of my good designs are also submitted to GiF, the chance that I use a ship nobody has seen before here on the forum is very slim.
Edit: I don't know any other Alpha by myself. So I don't know how good they are.
