I need 100's of spam removing from FB groups

I have recently taken over 30 Facebook groups, but there are hundreds of spam posts in each group and spam accounts.

I would like to make someone a moderator, to go through each group, delete the spam, and choose the option to "block the poster and delete anything else they've posted".

**DO NOT SEND A PROPOSAL WITHOUT FIRST BEING ACCEPTED INTO THE GROUPS AND SEEING THE WORK LOAD**

I would need the work to be finished by 5th April.

Please see the image attached for the groups. Here is an example link, but they all follow the same pattern.

The price is fixed.
