So I started to notice a few similarities between a group of users seemingly trading merit back and forth between themselves for poor to average posts or nothing really of substance. What stood out the most is that 99% of them are on the same two campaigns (or at least have their signatures) which seemingly require high merit and even paid bonuses for merit achieved. The campaigns in question are Yahoo's Eroiy.io and his own one:
https://bitcointalksearch.org/topic/eroiyio-signature-campaignhigher-rewards-for-users-with-meritsclosed-2827626 Eroiy.io Signature Campaign(Higher rewards for users with merits)(CLOSED)
https://bitcointalksearch.org/topic/yahoo62278-sig-avatar-campaignhigh-merit-requiredclosed-2956154 Yahoo62278 Sig & Avatar Campaign(High merit required)
I think it's highly likely that many of the following users are either alts and/or have at least conspired to trade merit between themselves to try get on these campaigns and/or boost their pay.
Upon looking at the first page of sign-ups on yahoo's signature campaign I see a lot of users who have seemingly been unsuccessful in joining that one and have at least attempted to sign up on Eroiy.io as they're all baring that signature. These two users who tried to join back to back with the same activity stood out especially:

https://bitcointalksearch.org/user/lenovo16-1111405 lenovo16 August 17, 2017 Eroiy.io
If you check their merit history you will see they have only sent merit to other users baring either Eroiy.io or Yahoo's own signatures.

Once you start to look into the others sent merit you rapidly start to descend down a massive merit rabbit hole of accounts who have seemingly traded merit back and forth between the same group of users all mostly on the same two campaigns.
Check out the merit list of the guy shalnark and lenovo16 both sent merit to:

With the exception of mharz all of the accounts he has sent merit to are yet again on both campaigns:

Starting to see a pattern here? The same names just keep popping up and the odds of that randomly happening are astronomical. If you check the merit sent of all the accounts above they've all pretty much just sent to the same group of members who 99% are on the same two campaigns that just so happen to require merit. There will likely be a lot of alts here (probably the ones that signed up in the same months) but it's hard to say which for sure without further evidence, but at the very least I think there's almost certainly been some behind the scenes collusion between members on the campaigns just to send merit to each other.

I could go on listing all the users in question but it should be pretty clear by now the ones that are involved. There's really no good reason why the same names should be popping up and even the same poor to below average posts getting merited by the same users. I think these users have some explaining to do.
