First of all, it was borderline harassment, and it was titled "an official statement", which you are in no capacity to make on Atlas.
More importantly, you announced your intentions to donate to a political campaign, in your name, based on the actions of another person. It was very likely that said person would read the post, considering the thread had his username in it, and that he made nearly 3,000 posts on Atlas in the past 365 days. Landslide Lyndon is the only person who is in complete control over his own Atlas activity, meaning that he would have been in a situation where he could decide how much to donate to a campaign in someone else's name, down to $0.25 precision, i.e. straw donations. Of course, if you never actually make the donations, it would've been just another one of your ridiculous threads.
Also, it would've cost you $686 by the Iowa caucuses. We would've demanded receipts. Even if those receipts didn't implicate you in illegal campaign donations (and it's not like the FEC or any other authorities would even pursue you over being an idiot), be glad the mods saved you the money.
