The ToS: Aside from the mis-capitalisations in the AUP, it's mostly fine. I'm not fond of 3,1,4 or 5,4,2,1, although they're both understandable.
Heh, both have solid reasons for being there. Too many people will either stop paying, or be terminated for abuse, and simply try to open a new account to avoid their history. I also see a good deal of people "opening an account for a friend", and there has never been a good justification as to why that would be necessary.
Now, obviously some folks might represent a company, and might want their company to have an account with us separate of their personal stuff. Perfectly reasonable, and we do allow 'business' accounts - they just have to be approved beforehand (typically, the user would get with me, I'll list out the info we need, and get the account created, whitelisted, and ready to go for them).
Rejecting unverified PayPal payments was a bit of a tough decision. We realize how many people dislike giving PayPal their bank/CC/etc.. but at the end of the day, unverified PayPal payments comprised less than 7% of our clients; while conversely, well over 95% of our abusive clients were using unverified PayPal accounts. That policy helped a great deal in thinning out abusers and payment risks (the folks that tried disputes/etc, and then tried opening new accounts anyways).
The PONY thing is an old joke originating from the FMP series. tl;dr - it basically turned into a company meme, fueled in no small part by our own community and IRC. While we do have some various equus-named items (the Stallion panel, etc), it's worth noting that the Pony antics only take place in community settings. We're not sending out Pony-themed invoices to folks
The stock thing was a bit of a phenomenon, to be honest. We had another brand before BuyVM (and technically, Frantech is still the 'parent' company), so we had a good bit of experience with what was needed for providing quality service. When BuyVM rolled out officially, we were offering specs, prices, and addons that nobody else had at the time - between that, and our own community participation and dedication to quality, made us unreasonably popular, to the point that we could deploy a full new rack of hardware, average hundreds of sales within half an hour of opening stock, and completely sell out the hardware within days. It became severe enough that people ended up staying up unreasonably late/early just to try and snag a VM, so we implemented stock control (releasing X quantities at specified times throughout the day) to try and help out folks in other timezones. It was honestly at the point where we would be completely sold out for months at a time, and we'd be so busy with support/tuning/etc that we simply wouldn't have time to even plan out hardware expansions.
So aye - it's "worked well" for us, and we're very happy that people enjoy the service.. but I can honestly say that none of us expected or planned for things to play out that way.
I must say though, it is very nice to see such open/unabashed criticism, especially constructive criticism. A simple listing of faults, WHY they're considered faults, all without personal attacks or any real bias other than just calling things as you see it. I tip my hat to you sir, the community (and market) needs much more of that type of open-eye critique.
