There are a number of pictures of Aloe vera which I believe are misidentified. The plant may have spots when it is young (ie. just a few leaves) but those go away once it passes the juvenile phase. Here is a picture showing how the spots go away as plants mature.
Aloe vera is just one of 500+ species of aloe and is quite often misidentified among sale plants. As a group the spotted aloes can be difficult to identify even with a flower, but Aloe vera is not one of them.
I have moved a few images already and am listing the remaining contributors who have submitted spotted plant pictures here.

Unless the plants pictured somehow grew up and lost their spots, I would recommend that the relevant photos be moved to the generic aloe listing until they can be better identified. Please let me know what you think.
