There are some suspicious things.
1. The account of Clokwise was created yesterday, the account of Sweguy was made yesterday too.
2. Both of them are from Sweden (Sweguy - the name tells it and also the fact that he uses Telia, a telecommunication service from Sweden).
3. Both of them posted some sort of info about Brotzu.
4. The confirmation about Sitri conference arrived too soon, the style of a message is also VERY SIMILAR.
5. If Swissguy, Clokwise and Sweguy are lying they may in be in cahoots or even the same person.
6. Why did 3 e-mails arrive in a single day?
but then
1. Clockwise's responses on a Swedish forum don't sound fake after using google translate.
