There are many sites like this one that are fly-by-night directories and scamming people. I am not saying that this is one of them, I am just saying beware.
I agree with you that there are a lot of them like that. I would not have used an example of one that you are not sure of though. This guy could be legit but you placed a cloud of doubt over him. It would be better to just warn that many of the link offerings on here could be just garbage and not worth your time or money.
Seems like many of them are buying and only you is complaining. Any proof on this? And as you said "I'm not saying that this is one of them" then why use that thread as a sample? Thanks please don't take this negatively I just want to hear your side. Thank you
