I’ve discovered a group of Memrise bots on this forum (20 at least), which I believe were created by the Memrise team.
have hidden profiles (some bug in the engine of the forum allows to view profiles from the post)
have typical profiles with short descriptions and smiles
were registered in the same periods or on the same dates
as it seems their main function is to like posts by Memrise staff
Here they are:
Some examples of how it works:
Comment by MemriseSupport (mostly liked by bots)
Post by luis_memrise (mostly liked by bots)
Comment by James_g_memrise (most liked by bots)
Profile of MemriseSupport (mostly liked by bots)
Here comes our princess Mila, unlike these bots she has public profile, but appears along them.
Joined Sep 12, '18 just few days before the first group of bots. Though, in her own words, she “does not speak English very well” and “not from Memrise team”, but speaks almost fluently on this forum and all the time she explains how Memrise works.
