Ben I can only speak for myself so will try to explain how I see it
Even IF someone is bashing a someone in a thread and list the breeder, owner or kennel name, it is advertising, negative, but advertsing all the same. Since TP is supposrted by advertisers, if a post conflicts with those advertisers, I edit it. With the bashng or flaming threads, I also try to look at it from the stand point of libel.
Then again, you have 2 different situations. Could the buyer be at fault in any of the situations with the breeder not aware of the flaming? If the breeder DOES stumble onto the post, we have pages and pages of posts that have no business being here of a private battle.
When someone is looking for a GOOD breeder and others try to provide info on a reputable breeder, again it's in conflict with the TP advertisers.
CHAT is a good tool for communicating the info without posting on the forum, no problem sdharing the info there.
Here are the rules, shown at the top of the page everytime you post
Rules: NO ADVERTISING! (NO "Wanted" topics, NO "For Sale" topics and NO Website promotion). NO "Vote for my...." or "Vote for me..." topics Topic must be pet related OR forum related! Please try to use clean language and good grammar. Turn "Caps Lock" off. Must be over 13yr old to use. Please treat others with respect. Respect the Moderators and our staff. Direct all "ADMIN" questions to the contact page
Unless it's a spammer spewing nothing but garbage, any time I edit a post, I provide a reason (only done when I REALLY think it's necessary).
The posts I delete are generally the empty ones from accidential double posts. The only others are those in violation of the rules where there has been ample warning provided to the poster who has replied so I KNOW they've seen the reason.
Same thing with new folks who start 6 or more threads on the same topic within minutes of one another because they haven't received a reply to the first one.
Anyway, that's how I TRY to do my part as a mod. Hope that helps.
