# Reputation Modelling - Safety Example
We showcase how memetic bridges help ride-share networks use a common system to determine the safety ratings of their drivers.
### Step 1: Articulating the Culture
**What are the networks trying to measure?**
Whether a ride-share driver is a "safe" driver
**What are the networks trying to do?**
The networks are trying to identify unsafe drivers.
**Why is a memetic bridge beneficial to this?**
It allows for the networks to share information, allowing for an unsafe driver in one network being identified as an unsafe driver in all networks
### Step 2: Modelling the Reputation
**How are you planning on measuring this?**
A binary system
Either safe or unsafe
### Step 3: Finding Relevant Communities
**What other communities are relevant to this?**
- All other drive share communities or systems
**Why would they benefit from participating in this?**
- It would prevent unsafe or unprofessional drivers from participating in their network
### Step 4: Designing the Reputation
**How would this reputation look like?**
- A simple flag system
- One unsafe in one ecosystem, a user would be flagged and be labled unsafe in all other ecosystems participating
### An Example of a Safety Reputation System
- The peaks represent when the user is flagged as an unsafe driver
- The first peak is the initial flag
- The second and third is when the flag is picked up within another community
- Although the score does decrease over time, it remains above zero indicating an unsafe flag
