- Is the account new? If it is, be weary of it. They will tell you a lot of times that they made the account for the coin itself and that they are 'a senior member'. This is usually false.
- If there is a team listed, with photos, then do a google reverse image search on each individual. If you find the same picture elsewhere with a different name and different type of business, then you have a malicious ICO.
- Look at the person's previous posts. You can tell a great deal about someone by looking at their posting history and the way they treat others. While this may not be 100% related to the ICO itself, you can be sure that a person treating others poorly & often has a harsh way about them, I would be careful buying into that persons ICO.
- Last but not least, use your head. If something seems 'off' or amiss about the ICO, avoid it. It is better to not have invested and 'possibly' losing out, then it is to invest and find out a month later that the 'dev' ran off with your money
Those are but a fraction of what you should watch out for. If you are unsure, read the threads posts. 'Feel out' the vibes that people are giving off about the ICO. Lastly, never invest more than you are willing to lose. Even a solid ICO can turn out sour for reasons that can only be seen in hindsight (look at the first DAO, for example.).
