Several years back, before I got banned from Mansilla's mess, I complained about a DAP seller (MP4Nation, in HK, I think)  -- that seller was apparently a H-F sponsor. [I bought the DAP new from MP4Nation, but it failed after 2 wks; I returned for service, and it went into limbo ]
After my posts (several of which H-F  mods deleted), the DAP seller's head-honcho contacts me via private DIRECT email, warning me that I wouldn't get my DAP back if I didn't settle down (I was always polite on HF). The email addy he used was one I ONLY used for H-F. Someone from H-F top mgmt (or Jude) had given mP4Nation my private info and  put 2+2 together, from my customer info).

I never got that DAP back. SOL $190

MP4Nation made a big deal about my posts on their forum, using my real name, and attempting to de-base/insult as much as possible--the same head-honcho who emailed me was the MP4Nation forum Mod, leading the troops to blood-lust . Not sayin' much: That forum is filled with the usual brainwashed brand-name-loyal fanboyz.

With that DAP ripped off, I got a very similar DAP from one of MP4Nation's Chinese competitors. That's lasted over 5yrs --still going!
MP4Nation is still around. Maybe they've improved. Maybe H-F has, too

Try getting off MP4 nations email list.  They have been spamming me for 6 years after I bought some Brainwavz Betas
