This Is The Flakiest Players Have Been From Roll20

[KorvinStarmast]

I recruited on Roll20 for a game once, to fill in around a couple players I already had. ...I simply don't recruit on Roll20 anymore.

I was recruited into a game in roll20, but that was due to our regular game going dormant and nobody stepping up to DM. That group needed one player, I did the interview thing, they decided to take a chance and I am still gaming with them.
D&D 5e Giants game, a Home brew, Tunnels and Trolls, and Blades in the Dark.
I recruited a couple of people I know from forums and another on line group to DM for a few of that group in Salt Marsh.

Finding people you already know and proposing a game on r20 is a good plan also: I ended up in my first RL 20 group that way when my brother recruited me.

It's a mixed bag, but one does not know who might be a good fit until one tries. One must accept that sometimes, it was not a good fit.
