If you think that is enough, then use that. Some people think HTTP is secure enough, others use HTTPS. Some people think having a password like hello123 is enough, others use a more secure password.
I think this should be copy/pasted into the darkcoin.io website FAQ
Also MUST post that DarkSend/DarkCoin does not endorse illegal activity since it won't be accepted by governments, it needs some disclaimer
Technologies do not have opinions.
DarkCoin is a brand, its technology is another thing. If you don't post that it does NOT endorse illegal activity, people are going to connect this brand with Silkroad etc. which is not favourable
That is your opinion. I think it's very favorable.
