q: did you revert #3189 (comment) intentionally?

[edit]
Oh, I see you did, I read the post later in the ticket :-)

its a shitty web site with no standards and awful design.
but on a best effort basis this indexer will have to do since there appears to be a desperate want for it.
but I tell you this, the first person to complain that it does not work with Sonarr will get a boot up the arse.

I tested as much as I could, given the limitations, so you can merge after the minor commits suggestions.
Thanks.
