in reality, I didn’t talk about difficulties or facilitates. I was only talking about consistency with the platform name. There are millions of sites that offer challenges, but few platforms that offer virtual labs with whole vms. Now, from my point of view, the challenges could burst on a separate site, for example “hack the challegne”, because they have little to do with the initial nature of the platform. But in order not to be extremist, it is good for me to stay here, but at least to keep the two things separate. I repeat, it’s not a matter of ease or difficulty, but simply of personal taste, I don’t like it and I don’t see why to be at the top I have to do it.
