I suspect that there may be an argument for removing the comments facility for photographs and just leaving the voting there.
The voting produces a top photograph for each month and I think that's a valid part of the site.
The comment on photograph feature has - in my opinion - been superseded by the ability to link photos directly into a forum post, where any questions are much more easily picked up on and discussed. This feature is very handy and is used quite frequently.
If the comments feature is thought to have been abused - and in my personal opinion it's getting close to that - then we'll have to have a think about removing it in order to concentrate on discussing photos in the forum.
If anyone does have any queries about photographs that they want answering, then I'd strongly suggest that they click the "Discuss this photo, *description* in the forum" link as that's going to get a much better response.
Note: the record of who voted for what and who left which comment is, I believe, held in the database, so the webmaster is able to find out who you are ;)
