So many people hear about bitcointalk forum from friends, families, internet and so on they where not given the full details of the Dos and Don'ts (the rules of the forum) of the forum.
Even if this is what happens, they ought to know that every online forum has rules and regulations that are used to govern the ecosystem.
Assuming they are also not aware of it, they can easily ask a question about it if they actually want to learn and the issue will be solved rather than doing something that will affect their reputation.
