Scammers are caught within the trap of creating an excessive amount of profit during a short period of your time, which isn't right. If most are aware then they're going to avoid being scammed because we aren't aware.
If you found that someone is offering an unrealistic profits which is not possible to earn in short time, then it may be a scam attempt and beware of it.
Be aware of scammers which means to check everything before taking decision. I mean everything, nearly fell on a scam yesterday.
What do you mean scammers check everything ?
It will be better if you can tell what exactly happened yesterday so that others are also aware of it.
