In addition to what Shinhwalee said, there has been several reports about this as noted here: Wall of Shame (Fall 2016 Event).

Also there has been several bootlegged versions of KC which vary slightly in either wording and/or contents but the UI is very much similar to KC. Here is one Japanese blog entry discussing about the clones/bootlegs that resembles close to KC. Many of those probably no longer exist but that doesn't stop one from re-creating KC and localising into their own tastes simply by manipulating game data that can be obtained fairly easily.

Last but not least, I want to also point out this very particular case with a game that was inspired by Kancolle (started as bootleg/clone) but later on created a new mechanic which some fans claimed was a copy that was from this game into the official Kancolle game. The name of the game is called Warship Girls. Fans from both sides (KC and Warship Girls) have clashed with each other in the past over the same issues that KC the franchise faces against all these inspirations
