You can give position as indexOf second parameter. This gives a plausible little case where you can figure out the length of a string without using length:
'abc'.indexOf('',Infinity)
Most likely useful use case I can think of would be when doing code golfing.
Other than that, I think the current functionality is perfectly fine. It is often a silly case, but I don't see a reason to block it. It does give a valid match to positions between and around characters.
Interesting idea using it to find out the length though that trick only works for JavaScript. In C#, you get an ArgumentOutOfRangeException unless you specify the start position to be within the length of the string.
I'm not sure how useful it would be for finding the position between characters as it can only tell you what the start position was.
For further actions, you may consider blocking this person and/or reporting abuse
