I gave this some thought and this is what I would do..
Post the property. with that being already done you are covering your tracks legally against trespassing individuals.
For those you gladly give permission to, know where their stand is, and be sure they follow your rules when it comes to hunting.
Remove your neighbors stands and confiscate them. When they come to you and ask why they were taken down reply they they are trespassing and no-matter what they had done in the past does not give them the right to continue to do this, especially since they already know you do not want them there.
At the same time, call your local police agency, have them come out, have a report filed, and make sure the police approach these neighbors so they know they were in fact trespassing and not wanted on your property.
Have them arrested if they continue to go onto your property.
I am not in law enforcement, nor do I always do the politically correct thing, but keeping their stands,(hey, the stands are on your land, and they should not have been there to begin with) may be a start, you will probably not be given the time of day by these people ever again by taking them and getting the police involved, nor will they help you out if needed, but they should get the message you mean bussiness.
You also will not be able to change their hunting habits, but if you practice good QDM, you may be able to keep some of these deer on your property where they will grow to what you want.
How do others feel about my response? This is what I would do if there where people illegally hunting my piece of land.
