It's fine to offer CONTSTRUCTIVE advice in an attempt to help someone, even if they did not specifically ask, but to tell someone to pour bleach in their tank is just way out of line.
By posting anything in a public forum, you open yourself up to critique, which is expected. But to blatantly insult someone will not be tolerated. You don't have to agree here, but you do have to be polite.
