I have seen at least 3 patterns of potentially abusive profiles/posts which may not be obvious to all.

1. Those inviting contact through email outside the site : typically used by the "Nigerian" 419 scammers.
I saw two "matches" today from profiles I had never seen. Both turned out to have very similar text in them. So I did a web search for part of the text ("no one that likes anything more than a social drink or two") and, surprise, found all results only on mingle2.com.

2, Those providing a phone number, urging to call directly: typically used to harass the real owner of that phone number.
I saw a post in the forums today by a (new) member urging others to look at their profile to find their phone number. While a quick reverse search matched the phone number with the name in the profile, there is no way to tell that the user of the profile is indeed the same person . If this suspicion turns out to be true, naively contacting the number could result in police being called. I have heard of many cases where girls/women are subjected to such harassment - the original culprit publishes their number and then only the men who call the number get involved in further complications.

3. Those offering "escort"/"massage"/call-girl etc services : I'm guessing this is not what the site is intended for.

So, my question is, should such profiles be reported?

I do report.
Often a day or two later...Profile account no longer active.
This place is full of scammers and they need to be run off to allow the 5 or so real people here a chance.

Best police are ourselves.
Keep our yards clean and the trash has to move on.

Mingles had, and still have a lot of scammers, report them all and at once so the site to get clear a little....
