Do I need to be "concerned" bout Big Pockets forum members?

[Jessey Kwong]

I am new to RE discussions nad the BP community. I just noticed people here are VERY open to helping and giving advice/guidance.  For some reason... I feel these are red flags, but maybe am wrong. I come from the online digital marketing world and attitudes like this mean they are trying to solicit their services or products to you...

Though I am so new, and perhaps this is just the common BP community culture that people are being helpful. 

Should I be concerned about these users and are there any warning signs I should take note of or be weery of - thank you for your replies.
