Often people who are just starting out come on these boards with a preconceived idea of what they're looking for and start lots and lots of threads. It's become sort of a red flag to people.
People give them good thoughtful advice and try to steer them in a direction that will give them the best chance of success, then end up feeling jerked around because the person ignores that advice by asking the same questions over and over until someone says "go for it!" (There's always someone out there who will tell you what you want to hear.) Here are a few of the biggest red flags:
1. Starting multiple threads, especially if they are asking some of the same questions or so overlapping that they appear to be avoiding answers the poster doesn't want to hear.
2. Asking about big species that shouldn't ever be kept in captivity (e.g., big sharks) is a red flag on its own.
3. There is also a history of people with no experience saying they are going to set up an extremely ambitious tanks. These people tend to disappear after a short time once they figure out that it's impractical.
This can be frustrating (and, apparently mystifying) for people who are honestly interested in doing the right things because people who have been around here for a long time have less patience when they see those kinds of things in a thread.
I'm not trying to lecture you, but you seem to want to know what you're doing that is getting a strong reaction. Hope this is helpful.
