One of Wordpress sites was hacked (for about 10 hours), and Google picked up 4000+ urls in the index. The site is fixed, but I'm stuck with all those urls in the index. All the urls of of the form:

walkerorthodontics.com/index.php?online-payday-cash-loan.htmloncewe

The only bulk removal option I could find was to remove an entire folder, but I can't do that, as it would only leave the homepage and kill off everything else. For some crazy reason, the removal tools doesn't support wildcards, so that obvious solution is right out.

So, how do it get rid of 4000 results? And no, waiting around for them to 404 out of the index isn't an option.

With Moz pro, it says I get 5. Is that per day? Month? Ever?

There are tons of businesses that share a street address with others (like at a shopping mall). I've never seen a problem where having 2 addresses the same affected anything. The suite A/B thing is fine though, even if it's only a placebo effect.

For our site, Google is suddenly reporting hundreds of 404 errors, but the pages they are reporting never existed. The links Google shows are clearly spam style,  but the website hasn't been hacked. This happened a few weeks ago, and after a couple days they disappeared from WMT. What's the deal?

I'm going with "Google is too smart for that" on the transparent image alt text front. I guess it would help out people using a screen reader, but I'd like to get some of the images into Google image search. It seems like alt text is pretty much required to rank for that?

We pretty much exclusively use background images for our sites. How do I add in alt text? I tried a Google search for this issue and the best answer I could find was "Use the 'title' tag in the containing div", but that was from 2010.

Is there a better way to do it? And no, we're not going to switch to using standard images, because background images are way more slick for UX.
