Is there a block or ignore feature on the site or the blogs?

Yes there is. Go to my account. Go down too friends. Go to the person you want blocked and hit that. Now they can still read your blogs under community. But no messaging and they can't see your suite. I just hit stop following. 

seems to still show up in the community blog listings...

I said that. They can still comment on your blogs. I ignore them. Some I ask nicely. I say p!ease stop following me and then I stop following them. When I see his comments I pass it by.

The software is as it is.

If I was blogging current 100 dollar bills out of my wallet and copyrighted images of animals, I would expect to be ignored and more...FWIW

Your 100% right. Its abuse.

How do you delete your account on this website? Rules say just stop using website if your sick of it? So many accounts are inactive for years but show profiles. It seems the ANA should just remove non members website profiles? Don't most sites have a delete entire account option? 

Yeah, if you aren't going to be on here, then delete your account.

Can't find a delete option? I don't think there is a way to delete. That is why there are 25,000 members on here, but many inactive for years? Doesn't really matter I suppose.  My membership expires in 2024 I believe.
