I wouldn't want 50 smaller limit accounts either because none of those accounts will ever get big enough to receive premium search placement. Also, logging in and out of so many accounts and working with 50 bank accounts would get to be a huge hassle.
That's why smart people use multiple VPS (Linux or Windows based ones), const. opened and minimized below. The experts (the smart of the smartest ones) use multiple desktops on their own PC, attached multiple portable browsers to each one, each one with an addon to maintain the IP, etc. - it's not for everyone, it eats alot of RAM (minimum 16 GB).
Spreading the risk into multiple small accs is a wise choice but all depends. Some day all of those "small" accs can be "mid" and then "big" ones. The other benefit is that you can
compete with
yourself. So when a buying search for "something_strange" keyword, he'll find 20 listings for X prices and 5 listings from your 5 x small accs with different prices (that will be put randomly between those 20 listings). So the chance a buyer could buy from you increases. You can have 2 x big ones with TRSP badges and compete on "Best Match", then 2 x mid accs on competing by sorting on "Best P&P Price", then 2 accs with auctions, etc. - there're many ways and different strategies.
I have seen one Chinese with main acc - 210k+ feedbacks and another 2 with around 44k feedbacks. Every listing that he list using his main acc - he copy it on the other 2 ones, of course totally different (stealth but with real info, real man) templates, skins, etc., only the prices are the same or different by few cents. So the's how "the smart CNs" operate. He even have few totally different websites from where he sale his stock but that's another story.
About the hassle - of course I don't recommend creating US-based accs, huh, or ANY other big/major country that "requires" a local bank acc. Alot of trouble. Withdrawing to VCCs is good and easy to accs that don't require to be confirmed a bank acc.
