As discussed on Discord, we want to improve the mature profile filtering by:

• Using a better list of words, from a third party (but that we can still edit if necessary).
• Provide a slider to choose the filter strength, between strong (1 word found flags the profile), normal (default, 3 words found), loose (5 words found).
• Make the filter re-parse a profile after some point to make sure the mature content is still here and the flag is still relevant.
