Correct, there is no difference in the code between the hosted version and the open source version. However, the hosted version does come with support ticket access and scheduled upgrades are free as part of the monthly fee.
We also handle set-up/install, as well as scheduled backups of the data both locally and externally.
I agree with this, I'd love to know how the categories are listed like that down the side!
Exodo theme is public on our github
Nodebb theme exodo, branch 2.0
Is a bit difficult to fit on another community cause you need modified widgets and some exodo tweaks but all is on our github
Is only compatible with nodebb 0.7.x
Been working on new version but not finished yet
@avi Hard to say, they could be doing it through cookies, if you upvote a deal, the upvote of that deal is saved into your cookies, then if you try again in the same browser, it knows you've done it already, however this is also circumventable by changing browsers and deleting your browser cookies. You can make it hard for someone to fake votes, but you can't stop it.
I think a mixture of email confirmation, cookie usage, limiting who can upvote and downvote (need to post a deal in order to vote for other deals, or something like that) and keeping an eye on activity would deter enough people not to bother trying to fake the votes.
You'd have to post the deal, log out, clear your entire browser cache, cookies, history etc, create an email account, sign up, verify your account, upvote, then do the whole thing again, the time taken isn't worth it, it would be easier to hire a team of people in the east to do it for you (similar to likes on facebook or views on youtube), and you can't stop them unless you place blanket IP bans on subnet ranges. Which, if you're only concentrating on one place, then that would be fine.
