I believe it would be the SEC, not the FCC. And, whatever the regs are regarding solicitation, didn't you just do it anyway? :D

If you're looking for people to invest into your business, such as buying shares in a corporation or units in an LLC, then you are selling securities. It comes under the SEC and state regulations. State regulations means the state where the investor lives, not where you live or the company is based.

Making a public posting would constitute a public offering. That is heavily regulated. You would need extensive legal advice and probably the assistance of an investment bank. You're doing an IPO. That makes sense if you're trying raise tens or hundreds of millions.

If you're just trying to raise millions, you can do a Regulation D filing. Depending on the details, that will let you have 10's of investors and raise a few million. Figure about $20-30K in legal fees.

However, with that type of filing you're limited to offering the investment to people that you have an existing relationship with. You could not make a posting here or anywhere else asking for investors.

As always with this sort of question, my advice is really worth exactly what you're paying. A good lawyer is absolutely essential for something like this.
