Indeed because not all that we hear and see are true so before we believe on them, it will be better if we double check it first by doing some research online although not all information scattered online are also real but still there must be sources which can be identified as legit like for example this forum, most topics and replies here are legit especially if it came from a member with a good reputation and rank is already high at the same time.

We shouldn't fall again on the same scheme or trap if we know that we have been on the same situation before. A few mistake would be enough already I guess? To be able to change yourself for the better.
