Thank you, @pharnal. From my point of view, please stay away from them. As I always say, knowledge is power and being forewarned is forearmed. I tried to fit this post all into one article but it was just way too long hence I had to split it into two so I do apologise for that. Didn't mean to leave it on a cliffhanger or anything like that as it did all end in a very serious way indeed.
Otherwise thank you so much for the great comment!! :)
