I am all of a sudden receiving the below error whenever trying to submit an album with more than 1 track. I had added several valid albums with multiple tracks in a row immediately prior to this error.

Internal error: Request was blocked by automated security. If you're filling out a new form, try entering only the minimum required fields and see if that helps. Otherwise, report this problem to the webmaster.

Here's some additional info from some further experimentation. The link below is the specific release I seem to be having issues with. I'm not sure if it's the name of the release that is the problem or something else. I am able to add releases with more than 1 track to other bands. I have also successfully added another album with more than 1 track to this same band after receiving this error. If I try to modify this specific album (Corrode) to have more than 1 track, I receive the same "automated security" error. If I try to add another album of this same name (Corrode), I receive the same "automated security" error.

The title of track 2 is literally a Unix command line... Understandably, the server security system finds that pretty suspicious. In rare cases like this, you can use HTML entities like I did to escape problematic characters.

Fair enough. I'll keep that solution in mind if I ever encounter a similar issue. Thanks for your help.
