I've been reading through one of the suggested policies linked to in the lousy canuck post:
Harassment includes offensive verbal comments [related to gender, sexual orientation, disability, physical appearance, body size, race, religion, [your specific concern here]], sexual images in public spaces, deliberate intimidation, stalking, following, harassing photography or recording, sustained disruption of talks or other events, inappropriate physical contact, and unwelcome sexual attention. Participants asked to stop any harassing behavior are expected to comply immediately.
OK - I suppose the notion I find hardest to take at face value is that following constitute harassment, but I will try to put to put myself in the scene...
I suppose that if I was at a con and someone took it into their head to continually follow me about - an overfriendly person whose sustained company I did not desire, for instance - I might start to feel uncomfortable and ask them to stop, and if the behaviour persisted I would appreciate help from the staff. As to whether an accusation of following is made against someone I think the staff could check that the request to stop was made, and ask it on behalf of the participant if they were too intimidated to do so themselves. I do think the followee also needs to be informed that the behaviour may not have been deliberate or malign in intent, and that unless it was truly egregious it does not constitute harassment unless it persists after fair warning.
If the follower insists the movement was coincidental there seems little way to prove otherwise, but it could be pointed out that giving the individual concerned more space would be better. If the followee raises another complaint I suppose the best way to sort it - logistics allowing - would be to check that the follower is actually persisting in the behaviour. Such checking could also take into account that the followee may be playing some sort of entrapment game. I realise this is hard to judge but most staff with half a brain should be able to work out if the putative followee is playing up. One last chance and then an escort from the premises seems understandable at this point.
I do think "sexual images in public spaces" covers an awful lot of ground. I would leave it up to convention organisers to decide what they deem a breach of good taste. I certainly would object to some kind of categorical eschewal of anything remotely sexual.
[Exhibitors in the expo hall, sponsor or vendor booths, or similar activities are also subject to the anti-harassment policy. In particular, exhibitors should not use sexualized images, activities, or other material. Booth staff (including volunteers) should not use sexualized clothing/uniforms/costumes, or otherwise create a sexualized environment.]
I'm totally lassez faire about this sort of thing. If you object to a stand with sexualised images (within the bounds of the law) do not avail them of your custom. I suppose that there might be something that's in such bad taste that a con organiser might not wish to be associated with it - I would leave that up to them.
If a participant engages in harassing behavior, the conference organizers may take any action they deem appropriate, including warning the offender or expulsion from the conference [with no refund]. If you are being harassed, notice that someone else is being harassed, or have any other concerns, please contact a member of conference staff immediately.
[Conference staff can be identified by t-shirts/special badges/head sets.] Conference staff will be happy to help participants contact hotel/venue security or local law enforcement, provide escorts, or otherwise assist those experiencing harassment to feel safe for the duration of the conference. We value your attendance.
No real objections - though I wonder if things like escorts are realistic of the logistics available at smaller cons.
[Email address for organizers]
[Phone number for conference security or organizers]
[Phone number for hotel/venue security]
[Local law enforcement]
[Local sexual assault hot line]
[Local emergency and non-emergency medical]
[Local taxi company]
Seems utterly sensible to provide this sort of information, perhaps as part of a flyer or programme people receive on reception.
