I used a transaction accelerator service here on the forum once, and right after my post the guy asked me to leave him a "review" on his trust page. I suspect that's the reason a lot of people start these services in the first place--to gain trust.
That's why it is "free". They are abusing someone else's service as they do not have the necessary means to actually have an acceleration service.
All the micropecker Asians will do anything to increase their girth and/or length, so to speak.
Is that kind of statement really necessary?

No. However, it isn't that far fetched and does sometimes entertain.
