Probably not. Most graffiti should not be taken personally. If you have graffiti on your property, it may simply be that your property is convenient to paint on. Don't assume you've been singled out. Also, do not be afraid to remove the graffiti from your property. Graffiti writers almost never retaliate against property owners.
You should, however, report incidents of graffiti on your property to 9-1-1. This will generate a police report and help the Police Department track activity patterns. That, in turn, influences our decisions on how to deploy our resources. Finally, experience shows that when graffiti is swiftly removed, within 48 hours of its occurrence, it is less likely to show up again in the same location. If the goal of the perpetrator is to gain attention, let’s deny them that and encourage them to move elsewhere.
