Did you check the website first before accepting their offer to hire you to promote this new website?
This is a website with a very well-known cheap script and there is bunch of similar sites with the same script as you can find in this gambling board, the latest is the one that implement lightning network.
What happened to these websites? Most of them are tagged with negative trust because of scam.
I do not mean to say that it will be a scam as well, but I think I should remind others about this fact.
I know you have nothing to do with this site as you are hired to create an ANN thread only, but I think you should be more careful in accepting an offer from a new gambling site.
Just worrying that it may affect your reputation.
Last but not least, how the raffle works? I mean how the site draw the winner? Is it using provably fair system or not?
Raffle game should be completely fair IMO and every result should be verifiable to assure players that there is no cheat in the game.
Now that you mention it, I remember a few platforms that are actually similar to what you're describing. Cheap script, no provably-fair system, and a very basic ANN thread wherein the main handle of the gambling platform here at bitcointalk can't even buy a copper membership to do a proper ANN thread. There are a lot of missing details here on this platform to be up to par with the current standards, most especially the website design and the lack of ways for gamblers to prove if the session is legit or not. Hopefully this site improves, but even if it does, I honestly don't think a lot of people will catch up to the nature of the game they're trying to promote.
