(I don't see a "3DSwym" dedicated community here, so I'll ask it in Enovia)

I've seen this a few times where there might be multiple options when @-ing a user in a 3DSwym post or comment. I imagine that in the case shown below, the multiple "Ilan Madjar" accounts might actually be the same person, but perhaps with different accounts/emails. 

How do I know I'm tagging the most appropriate person in my comment? 

Can I somehow see which email or username is associated with each suggestion and figure it out from there? 
Or, when there's not a picture associated with the profile, can the colors be somewhat randomized to better distinguish them (obligatory disclaimer about color blindness and accessibility)?
