The trust feedbacks left by joniboini explain everything.
joniboini_alt and elda34b are his alts (joniboini_alt is not anymore).
Not sure why there are a number of transactions involving different tokens between joniboini and Husna QA thou.
In his feedback left to Husna QA, he said that they worked together on some translation projects. Hence, sending coins to each other is reasonable. Besides, forum members are sending coins to each other all the time.
@op, having multiple accounts is not against forum rules. Unless they are used to join the same bounty campaign, excanging merits or trust farming. Why did you bring this up! Does it have something to do with them being good members and receiving many merits!
