I fixed the problem that was causing you to be unable to unlock your threads.
As far as the problem Ritchie brought up, I suppose that if someone sees an issue in a classified ad here, it will have to be treated the same as any other ad placed on another website somewhere else. Capture the image and paste it into the relevant thread on the BOI. Moderators can make a copy of the thread itself, if necessary, and post it elsewhere outside of the classifieds section where the author will be unable to touch it. If necessary, I can set up a special forum for this purpose.
Locking a thread should be the exception, rather than the rule. Let's face it, people look for ads with replies to them. Check the number of views any thread has gotten in the classifieds section with replies compared to other ads that have no replies to them.
If you want a large number of hits on your ad, well, people that are discussing you ad will simply attract attention. That's just the way it works.
Just be careful you don't heavily abuse that bumping option. If I begin to hear a lot of complaints from people crowded out due to several people continually bumping the same ads, I will have to discontinue this feature. If your product is not selling, maybe you just need to do a better classified ad and not keep throwing the same old one up in front of people thinking they aren't seeing it.
Need I tell anyone you MUST provide photos if you want to get interest? That's the way it works as well.
But without a doubt, the classifieds section will be subject to positive feedback. The more people who post ads there, the more people who will come to see them. The more people seeing the ads, the greater the likelihood that you will snag a buyer. But the sellers have to start the process for this to work. People ARE coming to this site, so YOU have to make the effort to provide the classified ads for them to look over.
And heck, it's for FREE! What more do you want?
