IP cap on downloading games too fast or too many

after many months of going through looking up each game to make sure its not same game on different console or same game but different country, looking up so so so many japan only games with no wiki to tell what it even is.... im finally at the end, only a few consoles left, 1 of which is wiiware, i usually bookmark a list of everything form 1 console at a time an go through bookmarking's looking up game an downloading or not, so on, well sense wiiware games are so small they instantly downlaod, decided i was just gunna download the 1,3000 boomarkings i made an delete what i dont want later..... well i found some sort of hidden download cap
