  Presented data contains the record of five spreading campaigns that occurred
in a virtual world platform. Users distributed avatars between each other
during the campaigns. The processes varied in time and range and were either
incentivized or not incentivized. Campaign data is accompanied by events. The
data can be used to build a multilayer network to place the campaigns in a
wider context. To the best of the authors knowledge, the study is the first
publicly available dataset containing a complete real multilayer social network
together, along with five complete spreading processes in it.
