Probably, they register on evil IP or get proxy ban. Usually, they need to pay small amount of money to unban it, but in some case, the evil unit is too high and it will cost a lot to get unban.
If you mean newbie that can't make post again after he post or reply thread, afaik newbie have a time limit before they can make post again.

Edit :
Whoops, looks like i missed that post, thanks for pointing out.

I want to use it but currently, coins that i want to trade still on "Coming Soon", idk why bitcoin in coming soon too, since it really popular and most of people use it.
I see a lot of coins that currently not available (coming soon status) and looks like it will have more than 200+(or probably 300+) coins and tokens that can trade or exchange on there.

Kalo agan ingin apliaksi yang support dengan pemabayaran IDR, gunakan Indodax. Selain bisa deposit dan tarik rupiah, ada banyak jenis koin disana.
Kalo agan mau lebih ke harga pasar luar, gunakan binance (kalo ga salah udah ada aplikasi andronya), tapi ga bisa tarik ke idr secara langsung.

Multi exchange.

Api exchange setauku hanya memberitahu harga koin di exchange tersebut, kecuali kalo agan punya auto trading bot yang butuh exchange api buat ngelakuin auto trade. (CMIIW)

Oke jadi gini, jika agan emang mau bikin ICO, agan harus mendapatkan izin dulu dari pemerintah (yang ku ketahui sih), jika agan sudah bisa meminta izin dari pemerintah dan diperbolehkan maka agan bisa lanjut ke tahap yang lebih mudah. Ya, karena minta izin tersebut cukup susah, apalagi hal yang berhubungan dengan crypto belum sepenuhnya legal di indonesia, beda cerita kalo agan emang mau buka ICO di negara lain seperti singapura.

Jadi, saya saranin pertama cari orang yang emang bisa meyakinkan dan minta izin pemerintah, terus kalo bisa agan ajak salah satu pemerintah atau orang yang terkenal di bidang peternakan di indonesia gabung. Sisanya itu lebih mudah daripada minta izinnya menurutku.

Good luck anyways.

You cannot sign message directly on their site, at least for now. But, if you have backup seeds, just import it to electrum and sign message from there or you can use BIP39 Iancoleman(use it offline) and write your seeds on there and just search your address, import the private key from address that you want to sign to your blockchain wallet via imported address and you will able to sign message from there.

The second way is more risky if your hardware have malware such as keylogger, so the first way is better.

What do you mean?

Looks like he got it from airdrops (the first time merit system was introduced) and seems he doesn't get any merit from then, if so then now he should have 46 smerit left now.
Smerit is half of merit, so 100 merit should have 50 smerit when the first time merit introduced and he already sent 4 smerit to other user.

No, the one that will decrease is sMerit, not the merit itself. For more information, try read Merit & new rank requirements.

Kayanya ada di antara dayanya, kalo agan ada teman yang punya spec pc serupa, coba di test di tempat mereka apakah bisa atau tidak, kalau emang masih tetap sama, saya saranin bawa langsung ke tempat servis terdekat, atau yang sekiranya bisa mengecheck vga tersebut. Mungkin akan keluar uang sedikit lebih banyak, tapi mending ambil jalan yang aman kalo emang agan benar-benar awam dalam pembongkaran vga.

Ups, maafkan saya. Soalnya dulu saya juga pernah punya domain yang .io dan harganya lebih murah dari yang .com (waktu ku check kisaran beda $20), jadi kukira .io juga lebih murah.

Umm.... alasannya cukup banyak, selain tergantung selera, .io juga lebih mudah di hafal daripada domain lain, karena mudah di hafal, orang akan jarang atau rada sulit terkena yang namanya phishing. Karena phishing pasti domainnya ga jauh-jauh amat dari .com dll.
Domain .io juga biasanya lebih mudah di dapat + harganya yang tidak setinggi domain .com atau .net dll (karena ku liat domain .com ada yang nyampe 50 juta).

Ya, ada beberapa alasan lainnya juga yang ku baca adanya tingkat keamanan lanjut yang mungkin berfungsi melindungi data pribadi investor. Saya sertakan linknya aja,

Idk why you still invest in them, they give you passive income daily from nowhere. Its to good too be true.

Same as above, binance is the best for affiliate program. They offer a reward too, so you will get extra income. But, looks like this kind of affiliate program will apply to other exchange too, so just pick exchange that make you comfortable.

More than 3% daily passive income, definitely 100% ponzi, imo. People should not investing on this scheme, even if this give high return but it will become scam.

Kalo bitcoin paling bagus pake ASIC, silahkan cari di forum section Mining di forum inggris, yang terkenal salah satunya adalah bitmain.com.
Kalo mau beli ASIC harus siap uang banyak + kapasitas listrik yang cukup besar, dan jika agan ga pandai mengatur biaya pengeluaran (listrik) dan perawatan maka akan rugi, karena 1 alat bisa kisaran 20 juta++.

OP mentioned will use token as payments, and AFAIK, yahoo doesn't accept token that still not traded in any exchange. If OP want to use bitcoin as payment or major altcoin, yahoo probably will accept it.

Did you using the right tag? Since you already contact support, then you should wait them to answer first. If can, they will return your XRP back to your address. If support can't do anything, then probably, you will lost your coin(looks like this is rarely happen).

Yes, that section contain such as altcoin exchange discussions, some altcoin price prediction and etc. But its contain ANN thread and some bounty campaign too, looks like trust need to show up on there.

Mining Section is only for discussion, so trust doesn't really matter on there except in local trade section or marketplace.
Example in indonesia, we already have Jual Beli section, which is same as Marketplace section on this forum and trust is showing up on there.

Mending pilihan pertama, aku juga ga maalah sama koin apapun atau token apapun, asalkan koin/token tersebut sudah bisa di tradingkan. Menerima pembayaran dengan token yang 'belum punya harga dan belum di tradingkan' terlalu beresiko, imo. Udah banyak project yang tokennya malah jadi scam.

Ada alasan lain, tapi karena ga mau nyinggung sebagian besar member disini, jadi segitu aja .

Ad channels? something like Coinzilla?
I never try crypto specific ad, but how about try to promote it on crypto forum? It probably will more effective, since you want to promote something that have crypto-specific on it. You can promote it in this forum too by auction, as long as you understand the rules.
