I've been earning 600+ likes every log on from the community at large.
The way I earn them is easy.
• Build Generators in areas near prepper stations that your own batteries normally run out at.
• Build bridges in helpful places
• Create helpful pathways
• Take down MULE camps to aid other people
• rebuild as many roads as possible, by raiding claim materials in Knots and by taking down big BTs, they normally drop 1000cc of Crystals.
• Build a safehouse near areas that normally have Timefalls and BTs, on too of that build a Timefall Shelter and upgrade it to level 3, this gives better repairs to people passing the time.
