Well, lets have an example if a person posts few posts a week and they are mostly spam posts and then there is another person who post 50+ posts in a week but all of them are good ones, then whom we will think is spam poster?
I think the quantity of posts have nothing to do with the quality of posts.
What I believe is that the conclusion you express does not follow from the premise.
At least in some cases, the quantity of posts does affect the quality. Someone who is a decent poster making 25 posts a week, if he enters a campaign like the one we are talking about and wants to reach the maximum payout, it is normal that on average his posts have less quality than when he makes 25.
I didn't have a main job I think I could easily write 100 posts or more a week.
And if "generic posts" are enough for the campaign you're in, you could do that on several accounts. That's a very decent salary in most countries.
Generic posts? I don't know for sure but I guess you do other things apart from writing in the forum, I don't know if it's a main job or what, but if you had no other job than writing in the forum couldn't you write more than 100 posts with decent quality? Normally you write more than 50, although some of them are updates of your threads.
This topic was created 4 years ago, and they're still paying spammers. I don't get it though: with their long-term budget and a bit more effort, they could hire users who's posts people actually read.
You are right: you don't get it. Do you think that the target audience of that campaign needs quality to drive them to gamble in the casino?
What is said is not nearly as important as how many times advertising appears on the forum. I know you don't go there as much as I do, but I can assure you that the average user is quite mathematically illiterate, something you can check in threads that the same people who wear casino signatures, who are also customers of the casinos, open. Like:
1) They have tried the umpteenth variant of martingale and think it is bad luck that they have lost their money.
2) They create a thread regretting having lost too much money.
3) They naively believe that with bonuses and promos, the house gives them an RTP over 100, lol.
And things like that.
