It would be great if CF could allow virtual participation in Live Contests. If user isn't in a mood of giving the whole contest or doesn't want his/her rating to be affected, it will be nice for them. It will also decrease the number of secondary accounts people maintain for giving contests for practice.
At least for me, motivation for participation in virtual contest decreases once the contest is over.
But there is something should be put into consideration, you can't be in a room with official participants.
I remember the good days when educational rounds were unrated and people would hack themselves...
Now educational rounds are blatant bootcamp ads which coincidentally serve as contests. How can we solve this issue? Virtual Participate!
We have Adhami say "But there is something should be put into consideration, you can't be in a room with official participants."
Well we can just separate them, BUILD a WALL! Look even donald trump is doing it, great work! Post this on 1e9+7 blogs to Make codeforces great again!
I agree that there should be option for virtual participation. However, it may be harmful unless studied carefully. This may include surveys on the reasons of virtual participation and the result of this on Codeforces community. You can't just put it right away.
