This just proved that Lightlord is dedicated to his marketing here in Bitcointalk with increased pay rates to motivate the participants to have a better output, we all know that having good incentives while posting here in Bitcointalk is a good motivation to post quality content, the rate is now competitive.
This improvement is good if the average campaign payout is still the same when this campaign is still active which is 60$ maximum pay for highest rank in the forum before. But right now the maximum earnings user can earn even on highest tier is just more or less 60$ for 60 post which can be earned by senior member rank with 20-25 post per week. Their current rate is still not that competitive but still it’s good that LL improve the pay rate.
I doubt this type of 60 post quota with low pay rate will improve the quality of post of participants that will max out the payment per week.
Current improvement is a good start to make up for their past issues. Bitvest is one of the longest running campaign before, LL's effort to spread the good image of bitvest will all be put to waste if he didn't make a move. Right now, it's up to the signature participants if they are going to apply/accept the offered rate or not. LL at least consider increasing a little bit rate per post and continue their campaign.
Regarding the quality of posts, it's BB's job to filter each participants. Starting from selecting the participants until they do their weekly quota, all posts will be scanned to avoid spam posts.
