After these last two days, I have come up with a short list of tells for ESL brownoid retards online:
>Uses ellipses too often, usually with a random number of periods each time
>Small trip-ups in grammar and sentence syntax
>Reddit spacing
>Has trouble understanding unpunctuated posts
>Refusal to post timestamped pictures of hands
>Gets upset when you call them out for being an ESL brownoid but won't do anything to prove otherwise
