There are several of the same issues we are always discussing here. And they are driving this little community nuts. I will not be saying here anything new which we haven't mentioned before. This is for organisation purposes only.
Bottom line, as volunteers our time is too precious to do something which a bot can easily do. So, I think we should consider suggesting to Viki to automate smarter checking of comments for the following:
1. General spam. Smart way to do this is to forbid any links in the comments. Yes we would have to upload the pictures rather than input a direct online link, but in my book it sure beats going manually through all the comments). Those comments would be instantaneously blocked with a explanation message saying links are not allowed.
2. Subtitle requests. (Whether in Discussion section or in the live comments.) Two-three keywords as filter would do. "Subtitles/subs", [Language], "want" or "please". Those a user could not post if first not re-directed to the form to ask for subs.
3. Review section used as comment field. (Probably the most irritating problem in my book.) The first sentence in the message with rules about reviewing should be: "Review section should not be used instead of the Discussion section. If you wish to comment on the show, please follow this link". And only after that, there should be an explanation what a review actually is and so on.
Offenders of the 1st point should be banned until further notice. (Viki staff review, profile deletion etc.)
Repeated offenders of the 2nd and 3rd point (3 times) should be placed "on ice" for a week first. Next three offenses - for a month. And so on.
