Yea, you really gotta watch any kind of an automatic page builder...they're more trouble than they're worth...and can easily get you into trouble.
I'm using Firefox...it's the only thing I'll review in...much safer for my systems. I didn't look at your code, but FF is generally much less forgiving of bad code. I'd suspect that you've got an open tag or two in there and that's what's causing your entire site to appear left aligned in FF. Would probably be worth your time to run it through a validator to find the error(s).
As to why that domain is on the spam list, no idea what you cause that on a new domain. I'm also unable to verify your hosting (not a good thing), but do see that there are 800+ other sites on that server. Perhaps there's some ip sharing going on and it's one of your neighbors that caused the problem. Maybe your host can shed some light on the situation.
On the subject of hosting, you'll want to make sure your hosting is verifiable through your whois also.
I know it may seem that things are unreasonably strict. But, you have no idea what kind of crap gets submitted to link sites every day
