Being a scammer!
Yeap you heard right! It is one of the less popular patch people take, but I'll show it is viable (I as myself don't do it, I'm just to honest to do it, but if people do it, I can infer that it has to be profitable!) and not against the rules (of course I'll not talk about getting onto someone's accounts, it is bad, remember!). I'll talk about 2 main, most popular ways people scam others!
First type of scammer you could be, is contract scammer! Now I'll show you 2 screens from the game how people tricks others!
Jita scammer
Here you can see one of the many jita local chat offers from the people! At first look, it sound like a very good deal (atleast now, because 1 plex goes for 6.1 million isk) and this guy offers you 6.9 Billion for 1000 plex! Next step probably new player would take is clicking into his offer that would look like this :
Jita scammer 2
And first glance it looks like that guy told the true, you want to click, but wait, you read and there is said that you'll get only 6.9 milion isk, not 6.9 billion for 1000 plex! That's how people scam others in contracts! They name tittle of the contract the way they want you to see it, but insides of contracts look other! You can coppy that to your own use! They do the same thing with blueprints( they want you to think that you're buying original but it is the copy) or with ships (especially the one's that have their counterpart in navy issue (let's say navy issue is tier 1+) like with the drakes!).
Second way people scam others is with use the addictive gambling ( yeap, in my opinion it is a scam, in the long term you'll lose) mechanic in the game called hyppernet offers! Now I'll show you one of the offers with gollem as a reward!
Gollem
Here you can see this offer, I'll shortly explain how hyppernet offers work, if you buy one of the hypernodes you have based on the randomnes chance to win the reward, like in this screen, there's 8 hypernoodes to buy so if you buy 1 you have chance 1/8 (12.5%) to win this. But let's calculate this thing out, gollem is worth around 1.5 Billion (the reward) and you have 8 hypernoodes to buy each one for 263.75 milion isk, 8x263.75 here we come with around 2.1 Billion isk! In the long term gambler will lose and you as the casino will be winner!
There's so many more ways to trick people, but I'll leave it to your creativity with game mechanics in your hands!
One of the challenges of being scammers it to be very appealing to people, to look like a honest guy so people would trust you. Second one connected with hypernoodes, is that you have capital to make those offerts! And here is my advice, sometimes people get very lucky, for example only 1 guy buys 1 hypernoode out of let's say 400 and he wins! So remember to calculate everything at to not put on the table as a casino too much! Another thing about hypernoodes is that you need to buy from new eden store for plex hypercore's!
