well if you want to avoid transparency, you can do what Doug Jones PAC did by the name of Highway 31

Working not with donations but unsecured credit.

Highway 31 has reported nearly $2 million worth of ads in the race, according to filings with the Federal Election Commission, making it the single largest independent spender of the general-election contest. The group filed what was expected to be its first itemized disclosure of donors and expenditures Thursday. But in the filing, Highway 31 said it had received and spent no money whatsoever.

Instead, the filing revealed, a handful of Democratic campaign vendors have produced and placed a number digital ads for the group entirely on credit. Though it disclosed no income or expenditures, Highway 31 listed debts owed to those vendors, and the amounts owed match up precisely with the values of the ads it reported to the FEC.

In other words, the group is financing its ad campaign on debt. A donor could step in after the race and contribute enough money to Highway 31 to pay off those debts. Or, alternatively, the vendors could choose to forgive the debts, in which case the services provided to the super PAC would be counted as in-kind contributions to the group, and require an amended FEC filing classifying them as such.

SHADY AS FUCK
