Hi <span class="h-card"><a class="u-url mention" data-user="@Antonela" href="https://playground.bonfire.cafe/pub/actors/Antonela" rel="ugc">@Antonela</a></span>, sorry it was a "me" problem because I could just (and have) completed the survey from a Windows computer at my university. But it’s also the problem that the Framasoft servers are de facto kinda large and well-known and thus are targeted by criminals through spam bots, who use the Tor network to stay anonymous, so Framasoft have to block Tor exit nodes.
Good to know that you were able to complete the survey! Each answer added us a lot. On the other hand it is good to know that about Framasoft.
