I didn�t see, or vote, on your contribution. So, I don�t know why it was reported. It�s not there now.
But maybe it was because it was numbers. Sometimes, if it is maths with no English involved, it is reported as not being an ESL resource. Maybe a moderator who remembers seeing it on the reporting page can confirm the actual reason because my hunch could be wrong.
Just to also let you know that moderators do not have to contact members and that anyone with 10+ points can report. Moderators only need to vote yes or no and comments are optional. In my experience, contacting members often results in nasty PMs back which is not very nice to get that when you are only trying to help.
If you think it should be ok, simply upload it again with a clear description of the English tasks involved.
