But worth reminding the councillors that if a Freedom of Information Act request is made (and they do get made), it could mean they may have to hand over ALL information, in all formats, including all of their social media, including all Private Messages.
It won't be up to the councillor to decide what is relevant, and if it is escalated to a full ICO case they could be put in place directions forcing the councillor to comply, thus damaging the councillor and the council as a whole. So they end up having to hand over embarrassing personal information to comply
Remember when a FoI is put in place it also includes ALL electronic communications, no buts not ifs and deleting electronic communications can result is a hefty fine, (Whitchurch Town Council in Shropshire). Destroying information that is subject to a FOI request is a criminal offence.
