According to an email sent to Brookline department heads and Town Meeting members, Brookline's town administrator Chas Carey is reaching out to residents to stop putting up the "Kidnapped" posters on public property in Brookline.
Brookline.news reports that the town sees the posters as any other unwanted public posting and has to take them down. This has spurred some of the poster hangers to follow advice found on TikTok to coat the posters in petroleum jelly and other slippery materials to make removal that much harder for Brookline DPW.
This seems to be what spurred Carey to action. In a statement to the website he said in part:
"The issue that prompted my outreach was not a specific message but a new posting method that made removal in the ordinary course of business difficult."
