In none of them have you shown any kind of proof about them being a scam or fake.
For certain I wouldn't buy even a power cable from them and I advise anyone to stick to the producer or the partners listed on the manufacturer website but when you advise against buying from somebody tell why we shouldn't.
I have a feeling you search google every day for miners and you come here and list every result you don't like.
I'm just trying to help people avoid scammers. If you put your brain to little contribution, you realized that there is evidence in my posts.
I looked over your profile and there is no day when you do not write something all over the forum even if you have no idea what it is talking about (do you want to increase your rank?)
Or is it about the advertisement in your signature to be seen by all the scammers who are trying to lose their way through the mixing service?
Is this your purpose?
Try to spend your free time in real life, make friends, girlfriend, look for a job. Cheers !
