I need some marketing tips for my website called “Would You Do It For A Do

I'm a developer, so I'm not good at marketing but I'm trying.

I came up with this, well stupid, idea. It's called "Would You Do It For A Dollar?". In simple terms: people can visit your profile and ask "would you __ for a dollar?", like "chug a beer", "twerk for 30 seconds", "french kiss person X"... Then you fulfill the request and earn $1. Simple as that.

What I've tried so far:

  • Post on Reddit, ProductHunt and Hackernews

  • Cold emailing

  • Ask people if they would like to include me in their newsletter

  • Have in plan to start FB ads.

Currently I have 100 subscribers. Can you please give me more idea on how to promote it. (I'm aware of everything regarding this project, I don't want to change the concept or MVP, it is the way it is, I just need some marketing suggestions)

Handling credit card info on site

Hi

I'm using European payment provider which is providing me API to communicate with them. There is a step where I need to ask from a buyer credit card info (number, expiration and CVV) so I can pass that info to that payment gateway via API.

Is that even allowed? How secure is that?

Targeting gay community online

Hi

I'm gay but not a marketer, I'm a developer. Currently I'm working on non-adult gay website/community. I'd like to get potential users before I go any further. I'm not sure where to start advertising.

I don't know many online gay communities, except for dating apps, but I don't want to go there. Facebook seems like a good option for advertising. I'm not selling any products or such, I'm not targeting any specific gay niche, my plan is to target gay community in general because the plan is to create private online community for gay people with verified members. It would be invitation-based system, meaning that you can only joined if you are invited by another member and once you are verified you can start contributing and s get full access.

Can anyone give me some tips?

Matching Specific Ad Based On Filters

Hi, I need a little help with someting I'd like to implement, but not sure how to do it.

I'm running eBay like classifieds site. There are a lot of filters on my site e.g. you can filter ads by price, by category, by city, by condition...
Let's say we have this use case:

  • User is able to filter ads on my site using filters
  • Once he does it he can save those filters and subscribe to get push notification when someone submits an ad that matches those filters
  • I save those filters in my database for that user

For this example let's say my site has around 100k active subscriptions.

The first step is obviously to attack a place in a code where ad is being saved to the database. I'm having a problem with how to know if that specific ad matches those filters.

I would need to go through 100k subscriptions and their filters to know which filter matches the ad that has been posted. It doesn't sound too good for me, it could be 1M filters or more.

Can someone help me with that or at least point me to the right direction
