Welcome back!

I missed you. Even started my own deep learning stash.

Btw, since you've been gone we've been having a spam problem. We delete the spams but they still show up in your notifications because right now we haven't programmed those to be deleted too.

Hi Adam - 

I see the huge spam problem - must mean you're successful that the spammers are targeting you - I really wonder how effective the spam must be. Are you tracking the click thru' on the links they provide. Can you identify a spam account by the fact they have high comment to post ratios and they have a single link in their comment? Have to assume they're bots. I don't mind a Captcha challenge before I comment - do you think that would stop them for a while (it feels like fighting Zombies). 

So assuming you can't block the spammers as you have no way of identifying them until they begin to post - and maybe even then by the time you catch them they've created another account. What about giving them the tools that will tell them they are wasting their time. Like Quora, show views and maybe clickthrus. 



BTW - Nice that I was missed - I've been posting food and stuff as Gammydodger though. I've been on various trips and data adventures - and building a tool for the 'citizen data scientist' to find value in the open data without having to write any code. Will tell more when we release in a couple of months. 

I've shown them that they're wasting their time but the problem is it's a multi level marketing scheme that keeps bringing in new hopeful naive people to post new comments. 

So for now it's a ban-and-delete strategy. Someday machine learning will allow bots to deal with it instead.
