Trying to hire a provider for services they advertise by contacting them is perfectly normal. Following up or asking again is also normal, especially if they haven’t got back to you from the first time you reached out. If they haven’t got back to you by the second or third time you reached out, it’s safe to say move on. It’s good business for a provider to respond within a reasonable timeframe, even if it’s only to say, “sorry I am booked up for the day you requested, but here are the next times I am available”, something like that. No response past a reasonable timeframe might indicate they are already overwhelmed with business and don’t need/want yours. Or they’re poor communicators, or flaky, or any number of things you probably don’t want in a provider anyways. It’s a bad sign. If they can’t do you the courtesy of responding, you probably shouldn’t hire them. Keep in mind sometimes it can take hours or the next morning for a provider to respond. Days without a response is unacceptable. Here are some scenarios that a provider might choose not respond to: Demanding dick/ass/nude pics, especially if the provider is not an escort, or if all of these are posted publicly online. Writing impatient or angry remarks in all caps because the provider was working and did not immediately respond to a text within minutes. Rude or disrespectful comments, racist/sexist and similar remarks. Incomprehensible texts. Texts that seem like someone is drunk/high (it has to be pretty bad for that to shine through over a text). Texts in a language the provider doesn’t speak. Texts asking the same questions over and over, that the provider has already answered. Unreasonable requests, for example: asking a provider to travel hundreds of miles away within a few hours, for a 1-hr appointment, with no previously planned travel arrangements. If you’re communicating something that’s a big red flag to the provider, that may be the reason. Any of the above merit some response, even if it’s a brief statement saying the provider can’t/won’t see the client. A lot of providers just don’t have the patience or emotional willpower to do this, however. Not a good excuse, but it happens. Some known clients are blacklisted for being violent, not paying, or for other legitimate reasons. Sometimes it’s best for a provider to not to engage at all with someone they know is problematic based off the lists or other intel telling them the client is bad. If you’re being normal and reasonable and the provider is not responding, it’s their loss. You’re paying, so that’s lost business for them, and an opportunity for the client to seek out a more reliable, responsive provider who wants their business and is willing and able to work hard to get it. ‘Stalker’ may not be the best operative word for what I think you mean. When I hear stalker, I think someone is going out of their way to invade my personal space, find out where I live, where I work (i.e. at a day job), research and track down my family, unearth sensitive personal information, threaten me, follow my movements in public, harass me, and so on. Same goes for harassing over text, or being aggressive, not respecting ‘no’ for an answer, demanding things, trying to contact me after being blocked on multiple platforms, and similar obsessive behaviors. If you’ve reached out multiple times with no response, and you’re not ticking any of the red flag boxes, you’re definitely not a stalker, but I would seriously consider hiring another provider. Professionalism and respect are the minimum a client should expect in a good provider.
