Now any and all posts I try to make are getting auto [dead]. I tried to make an account to stick with without throwaways and the comments are getting autoflagged.

You've made dozens of HN accounts (if not hundreds by now) , most of which have been breaking the site guidelines badly. That's way beyond the pale, and the bulk of this community would be appalled if they knew about it.

If you've had a change of heart and genuinely want to use HN as intended, we'll be happy to help you out. Here's one way to do that: (1) pick a username you want to stick with (without any trollishness like "truth hurts", etc.), and use only that account going forward; (2) post comments that stick to the site guidelines; (3) email hn@ycombinator.com and we'll review the comments and restore the comments that stick to the site guidelines. If that pattern becomes consistent, we'll be happy to remove any restrictions on your account.

You must have me confused with another user or multiple users from this IP range. There's no way I've made hundreds of accounts here. That's madness. There are probably other users in this IP range that are [dead] now.

I will take your advice and make another account from a different IP range and start new and within guidelines. Probably won't deal with [dead] there. Or should I try to use the unban feature for this IP?

Like I said, I'm happy to help—we're always happy to welcome any user who sincerely wants to follow the guidelines and use HN as intended going forward—but just to be clear, you'll need to follow all the steps in my previous comment for that to reliably work. Particularly step 3.
