There is no need for such a subforum because it will turn into a spamfest very quickly. Maybe your intentions are honest, but as you say yourself, there are too many scams and the place you propose would be ideal if they were promoted even better.

I suggest that you start your thread or more where you will deal with the airdrop topic, and possibly give some guidelines on how to recognize risky ones. Over time, if your thread proves to provide relevant and useful information, it will definitely be noticed by other members who are interested in this segment.
