"obviously not good to publish a personal address but it was nipped in the bud " No, it wasn't nipped in the bud. Ten times nore people will have seen that address than registered for the non-existent "party" and they won't have forgotten. Her neighbours know it already, but she can hardly go in and out for the messages, school run etc incognito. Now fanatics all over the UK know exactly where she lives, and can look on Google Maps to find the layout of the street and plan whatever fanatics plan for political targets. That could be pepper spray, an armed ambush, a kidnap, if you can imagine it, someone somewhere has already thought it a good idea.
If you worked in some job where you could make enemies, would you like your address plastered all over Facebook with a suggestion that those reading it should meet up there at midnight with a few bevvies in them? No, it is not a giggle.
bevvies = drinks
messages = shopping
