They cannot stop Bitcoin, by shutting down Bitcoin related websites. A lot of people have tried this before with peer-2-peer networks and they were unsuccessful. They might
slow it down, but they will not shut it down completely. People just find ways to circumvent these bans, by using Tor or moving hosts or using alternative ISP's.
Social media is also a very popular media to use, and also classified sites like Backpage. People will just go underground, if they go through with the banning.
They will slow down the average joes trying to get in the ecosystem tho, most ignorant people don't know what Tor is, or a VPN, so they may not get around that. I will hope that the more techy guys help the less computer literate guys so together they can bring Bitcoin in the spotlight where it deserves to be instead of the filthy economy they have on that poor dictatorship ruled country.
