Leaseweb says they don't allow warez/torrent hosting, but there are still soooo many warez/torrent sites that use their hosting, and have been using them for a couple months since leaseweb started saying they don't allow those types of sites. I honestly just think they say it incase It's someone from BREIN asking, but who really knows.
Honestly, I've had a couple servers with them before, not recently though, most recent was ~6 months ago, before all the stuff about them not allowing warez/torrent anymore, and that time and the few times before that, I ordered using fake info, and the order went through. Leaseweb used to be the type of hosts that didn't ask questions aslong as the money was there, however I'm not sure if they're still like that, so best advice I can give you.
Also, be wary if you order after a couple days into the start of the month, there will be a 25 Euro BS surcharge about ordering between payperiods or something. I'd say order the second or third of the month, I did once and didn't get the surcharge.
