I also agree with what your saying. When i first started keeping fish i made a mistake and bought a rtc thinking i could keep it in a 55. I learned my lesson and gave it to somone else who could give it a better home. Now i try to take full responsibility for all my fish and keep all that i can care for.
This forum taught me a lot of what i know about aquariums. I probably would still be keeping africans in a 20g without a heater and filter without it. Not to mention posting photos of my fish and meeting lots of cool people, as well as contributing and helping people out. A ban for young people would be a rude slap in the face, yes there are some immature members on here banning them, what happened to patience? When I first started posting on fish forums I'm sure I was worse than them
