The 1 sMerit TX looks suspicious. At least meriting a post for social reporting seems odd at best. Yet another example that goes against the whole aim of the Merit System.

The @lyka case looks pretty clear: He’s sent 150 sMerits to @lybship53 in just 5 merit TXs between the 13/07/2018 and the 20/11/2018. More than a one time 50 sMerit present to "his wife" (which is also not acceptable).
The other big TX performed by @lyka is one of those you get, whereby the Ann thread owner get merited. Normally this happens when the meriter participates in the thread, which is not the case … but @lybship53 did post on that same thread (and was merited there by @lyka). This TX is more difficult to classify, and sometimes it is done to give more credibility to the Ann thread where one participates. Even so, it’s another 50 sMerit TX …
