good morning! i think i have a fair share of exp as someone who frequently do fansupports since 2016.
1. although intended as free, sometimes, a portion for trades is also present. but this doesn't mean that the person didn't make sure to make as much as they can to giveaway without something in return.
2. "for trade lang po" line is usually used after a mobbing experience OR IN THE MIDDLE OF A MOB. i will personally say na for trade nalang ang freebies lalo na if people would swarm over you like there's some apocalypse. it's traumatizing. i had to pull away some random carats (and fans from other community) in events / concert just so they could get out of these situations. another scenario is literally because ubos na talaga yung intended portion na for free, so we're very sorry if that's the case.
3. some people are ungrateful, manghihingi tapos ipangt-trade sa iba. nakahingi na one time (when there's a variety to choose from), babalikan ka parin to attempt makakuha ng ibang design. which i personally find rude lalo na if clearly stated na 1:1 so that as many fans as possible ay makakuha. hindi naman madamot, but if you wanted more you could've just asked if it's possible.
4. some people who wants to get freebies ARE JUST PLAIN RUDE. not everyone, but you will really encounter entitled people that will give unsolicited remarks first before accepting what they're asking for / what you'll give and will test your patience because they do really get physical sometimes. they will force theirselves for it and sometimes sila pa yung mareklamo. if you don't want the item, don't even try to ask for it nalang po.
5. lastly, expecting something in return for your hardwork and effort despite other difficulties encountered outside of your stan life is okay when you give more naman. ☺️
