I think it is important, once in a while, to call this company by their proper name.
Machinima comma space inc full stop
Machinima, Inc.
Reasons.
1) There's always a chance it may annoy them.
2) It is a reminder that they are only a part of the machinima world.
Personally I imagine the company setup went like this;
"What, we can't use machinima as our company name, WHY WHY WHY is the world against us?"
"Ok ok, calm now, just type anything in the form, try using capital letters"
"What?!?!"
"Use stars, spaces, ascii anything."
"What's wrong with M*chi_nima Ltd as a company name, goddam stoopid law makers."
"Holy clutterbucks, I've spent a whole seven minutes on this form already & I've got company policy and employee contracts to copy and paste from 'shady employers dot com' before I get on with designing a hawt shiny logo."
"Right that'll do. No, I'll add a comma, it looks classier."
"Aha, business is easy, and still plenty of time left to go troll on the forums using my hilarious alt, sorted!"
