Advertising Via Google, generates a small amount of income, that goes towards the cost of providing this resource.

I am afraid that sales of the compiler are very low, the margin made on compiler sales does not justify providing this resource.

I want to keep this resource Free to access and Free of charges. I don't want to have to dedicate a large amount of time and resource running it.

Thankfully , the existing moderators keep spam at bay and notify me of issues that I need to attend to.

The current level of income from advertising, plus the support of moderators, makes a cost effective solution for me.
