iNat does not remove records of users. Records that are a serious violation of the terms of use may be hidden or the photos removed, but this is reserved for offenses such as spam, copyright violation, pictures of human remains, etc.
[edit, because I thought this post was part of a different thread] You might see some of the responses in this other thread for a variety of perspectives on why people might use the same photo for multiple observations. It is allowed – there is even a “duplicate” option on observations. In some cases (different species in the photo) it is even encouraged. Some uses are somewhat annoying for IDers (a new observation for each of 10 birds of the same species in the photo), but people often have personal reasons they choose to do this and the practice is not forbidden.
