I thought that these accounts had been abandoned but I saw one today that had reactivated and started posting again:

Last post was on August 12, 2018 then starts again on October 08, 2018. It's a similar story with all the others. Stop posting in August and either reappear recently or have yet to be active again.
The first one I spotted (Aidan_Davis) has been inactive since August 20, 2018, 08:15:36 PM

But his "sister" hasn't:

"She" was inactive since August 12, 2018 to October 12, 2018.
Interestingly she made this thread on the 16th:
As of August 2018, there are over 1600 cryptocurrencies that exist, according to Wikipedia. I know that Wikipedia isn't the most reliable of sources because anyone can edit it whenever they want, but the point is the number of cryptocurrencies being introduced. Some of the new cryptocurrencies I've heard were DeepBrainChain, ByteCoin, IOST, and Elastos. There's also a new coin called
Virie, which is apparently a cryptocurrency used to crowdfund and jumpstart the Virternity Project, a project that aims to digitized our minds, economy and the society. I believe that not all new coins aim to scam people, but do we really need more cryptocurrencies? Do we need new cryptocurrencies for every project that exists? Why can't there be one or five cryptocurrencies that all projects can use?
If we look a few posts down in that thread there's another one:
I have to agree with this. Not all projects would work on other existing coins such as bitcoins or ripple or other altcoins. Some needs a specific coin to run their projects, like DeepBrain I think and Virie. That said, I wonder how people would react to too many coins if and when cryptocurrencies became a worldwide digital currency. Do you think that people will be open to the idea of learning about different coins for different purposes?

Gap from August 12, 2018 to October 12, 2018
I wonder if they've been created to shill for DeepBrain and Virie (amongst others)?
