If you have never had the pleasure of being raided by bots, it is always a life experience when it first happens. It's only natural to think some personal side project would not be something to attract someone's attention to bother in this way. It's also a learning experience to finally realize that there are people that absolutely are willing to do this just because they can and/or just to see if it can be messed with. Also, never underestimate that your side project might land just right with someone that has a bone to pick and your project gives them the avenue to do it.
If you've never experienced any of that, it is very easily dismissed or flat out never even considered.
