This may be unpopular with some but personally I’d keep the witchy stuff off the profiles and save it for when you’re actually talking to someone you’ve built a bit of a bond with- no need to hide it but maybe don’t make it the first thing someone sees about you? Unless you’re lucky enough to meet another pagan, people tend to shy away from the unknown or (as you’ve unfortunately seen) make assumptions and take the piss. Pardon my Francais.
Manifestation tips? HA I don’t know about that - there are a few nice love spells dotted about here on the forum and website. I’m feeling pretty connected to my Sugar jar at the moment 
I’ve been having some banter with the Universe lately 
gently trying to encourage an ex to get back in touch… the Universe has sent me 3 exes in the last month and I’m like, ‘Babe, no. Not these guys, but thanks?’
