A tour operator that I used last year and which turned out to be a disaster, has emailed me using my personal email. When posters ask about the tour operator on the forum that I use, I give my opinion. The tour operator has asked me to stop because "it is damaging his business". A couple of questions:
1) is he allowed to contact me on my personal email like this? (he has my email because I had to give it when I booked the 6 week tour)
2) Should I stop giving my views when people ask? I am doing something wrong?
