Twitter ruthlessly rooted out the duplicate accounts of a friend who was using one for himself and one for the hillwalking group whose Facebook page he moderates, and has banned him from returning. So I don’t see why the Russians can get away with destabilising the entire western world (Russia backed Brexit in fake Twitter posts, 15 November). Our group only wanted Twitter for last-minute meet-ups and weather-related cancellations – we had no intention of recruiting the hillwalking community for nefarious purposes, even if that were possible.

• Twitter posts from Russia to influence public opinion sounds very much like Radio Free Europe and CIA-funded magazines in Europe during the cold war. Only the media has changed. Russia is only doing what we taught it.

• I realised after reading Wednesday’s letters page that, apart from a timely letter from the Forsdick grandchildren, all had been written by men. Come along, now, you can do better than this!

• “Swaths of the UK were blasted by icy temperatures” (Cold snap gives Britain its first taste of winter, 14 November)? Cold enough to freeze the Es out of swathes?

• By complaining about new ways of using “fulsome” and “fortuitous”, Maslanka and Sally Burch (Letters, 14 November) infer that semantic change should be halted and the meaning of words should not evolve over time. I think they have seriously underestimated the enormity of the challenge. I am literally bored to death of this debate.
