Same, I was really tempted and even tried to find some "generate fake phone number" sites but surprisingly couldn't find any. I really want to give it a try and join the fun everyone's having but I'm not giving my phone number away just like that.
Unfortunately these companies have caught on to the fake phone number workaround and don't allow VoIP numbers anymore. Fucking shame on them. There are dozens of other ways to verify legitimate users that don't require giving out personal information for no reason.
