I finally got around to testing this and as I expected it is crazy fast at indexing. I run a few test batches of premium social network links made in RankerX through the service and within minutes around 70% were indexed with this raising over the course of a few hours to over 90% indexed for most of my test batches. I have seen very similar indexing percentages and time frames for both auto generated content spins and manual content spins.
SER link indexing rates will always be all over the place no matter what you do due to the different types of platforms and the domain quality but I pushed a batch of links made up of nothing but BuddyPress, Drupal, Joomla (actual Joomla not K2) and WordPress links through the service and just over 40% were indexed within minutes rising to around 75% after an hour. This service has brought black hat indexing back to the pre-patch era of 2015's instant indexing.
It currently does have one unavoidable drawback and that is the captcha costs. I'm guessing all captcha requests are ReCaptcha V2 and 2captcha have a higher tarriff for them. If you are using mass automation (i'm talking tiered link building with tens of thousands of links) for your backlinks then the cost of captchas could cause problems but if you are trying to push smaller numbers of web 2.0s (a few thousand) or guest posts then this service is perfect.
I have a few projects set up with 10-100 T1 web 2.0 links with a T2 around the 500-1000 count that I have pushed through this service and I am looking forward to seeing how they react in the SERPs. I have just checked their indexing rates with scrapebox and the hand made T1 web 2.0s have 100% indexed on most batches with around 80% indexed for their automated web 2.0 tier 2 and they were submitted around 12 hours ago.
The interface of the service is clean and very easy to underland even if you are brand new to SEO/IM with little to no oportunity for the user to missclick something and screw things up. Excellent service OP
