Stalking by Texts

I feel a bit stalked.

Whenever I log in online I get a message appearing that says "soandso has received a text that you are online." I don't know the users who are getting these texts. They just added me as friends, and because they did that while they have their phone set up with Alacrity for text alerts and the like, they get to stalk when and when not that I'm online.

I think it's great some people what to know when their friends are online, but I don't want random strangers to whom I never talk to be able to stalk whenever I'm online. This could get out of hand very easily, it could mean someone who doesn't like me could come online and harass me whenever they got that alert.

It would be nice for this "alert" system to have a few modifications. Like only if you've both friended each other should the person be allowed to get alerts, not just a user friending you and now knowing your every move. And the ability to turn off user's being alerted to your online status via text. My friends don't need to know when I get online, they already know because I log into IM clients I share with them. The text is pointless for them.

I don't have my phone attached to Alacrity because frankly I hate the darn thing, so I don't know if there's some abilities for them to turn off the texting feature as well. That really applies to my friends online, as I still don't want virtual strangers to have a choice to know when I'm online.

So, that's my suggestion.
